General Description
The MCP1701 is a family of CMOS low dropout (LDO), positive voltage regulators that can deliver up to 250 mA of current while consuming only 2.0 A of quiescent current (typ.). The input operating range is specified up to 10V, making it ideal for lithium-ion (one or two cells), 9V alkaline and other two and three primary cell battery-powered applications. The MCP1701 is capable of delivering 250 mA with an input-to-output voltage differential (dropout voltage) of 650 mV. The low dropout voltage extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum VIN - VOUT differentials. The MCP1701 has a tight tolerance output voltage regulation of 0.5% (typ.) and very good line regulation at 0.2%. The LDO output is stable when using only 1 F of output capacitance of either tantalum or aluminum-electrolytic style capacitors. The MCP1701 LDO also incorporates short circuit protection to ensure maximum reliability. Package options include the 3-pin SOT-23A and 3-pin SOT-89.

VR is the nominal regulator output voltage. For example: VR = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V. The input voltage VIN = VR + 1.0V, IOUT = 40 mA. TCVOUT = (VOUT-HIGH - VOUT-LOW) *106 / (VR * Temperature), VOUT-HIGH = Highest voltage measured over the temperature range. VOUT-LOW = Lowest voltage measured over the temperature range. Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.

3.1
Ground Terminal (GND)
3.3
Unregulated Supply Input (VIN)
Regulator ground. Tie GND to the negative side of the output and the negative side of the input capacitor. Only the LDO bias current (2 A, typ.) flows out of this pin, there is no high current. The LDO output regulation is referenced to this pin. Minimize voltage drops between this pin and the negative side of the load.
3.2
Regulated Voltage Output (VOUT)
Connect VOUT to the positive side of the load and the positive terminal of the output capacitor. The positive side of the output capacitor should be physically located as close as possible to the LDO VOUT pin. The current flowing out of this pin is equal to the DC load current.
Connect the input supply voltage and the positive side of the input capacitor to VIN. Like all low dropout linear regulators, low source impedance is necessary for the stable operation of the LDO. The amount of capacitance required to ensure low source impedance will depend on the proximity of the input source capacitors or battery type. The input capacitor should be physically located as close as possible to the VIN pin. For most applications, 1 F of capacitance will ensure stable operation of the LDO circuit. For applications that have load currents below 100 mA, the input capacitance requirement can be lowered. The type of capacitor used can be ceramic, tantalum or aluminum electrolytic. The low equivalent series resistence characteristics of the ceramic will yield better noise and PSRR performance at high frequency. The current flow into this pin is equal to the DC load current, plus the LDO bias current (2 A, typ.).

4.0 DETAILED DESCRIPTION
4.2 Input Capacitor
The MCP1701 is a low quiescent current, precision, fixed-output voltage LDO. Unlike bipolar regulators, the MCP1701 supply current does not increase proportionally with load current. A 1 F input capacitor is recommended for most applications when the input impedance is on the order of 10. Larger input capacitance may be required for stability when operating from a battery input, or if there is a large distance from the input source to the LDO. When large values of output capacitance are used, the input capacitance should be increased to prevent high source impedance oscillations.
4.1
Output Capacitor
A minimum of 1 F output capacitor is required. The output capacitor should have an ESR greater than 0.1 and less than 5, plus a resonant frequency above 1 MHz. Larger output capacitors can be used to improve supply noise rejection and transient response. Care should be taken when increasing COUT to ensure that the input impedance is not high enough to cause high input impedance oscillation.
4.3
Overcurrent
The MCP1701 internal circuitry monitors the amount of current flowing through the P-channel pass transistor. In the event of a short circuit or excessive output current, the MCP1701 will act to limit the output current.

THERMAL CONSIDERATIONS
Power Dissipation
The amount of power dissipated internal to the LDO linear regulator is the sum of the power dissipation within the linear pass device (P-channel MOSFET) and the quiescent current required to bias the internal reference and error amplifier. The internal linear pass device power dissipation is calculated as shown in Equation 5-1.
To determine the junction temperature of the device, the thermal resistance from junction-to-ambient must be known. The 3-pin SOT-23 thermal resistance from junction-to-air (RJA) is estimated to be approximately 335 C/W. The SOT-89 RJA is estimated to be approximately 52 C/W when mounted on 1 square inch of copper. The RJA will vary with physical layout, airflow and other application-specific conditions. The device junction temperature is determined by calculating the junction temperature rise above ambient, then adding the rise to the ambient temperature.
EQUATION 5-1:
PD (Pass Device) = (VIN - VOUT) x IOUT The internal power dissipation, as a result of the bias current for the LDO internal reference and error amplifier, is calculated as shown in Equation 5-2.
EQUATION 5-5:
JUNCTION TEMPERATURE - SOT-23 EXAMPLE:
EQUATION 5-2:
PD (Bias) = VIN x IGND The total internal power dissipation is the sum of PD (pass device) and PD (bias).
T J = PDMAX x R JA + T A T J = 116.0 milliwatts x 335C/W + 55C T J = 93.9C
EQUATION 5-6:
JUNCTION TEMPERATURE - SOT-89 EXAMPLE:
EQUATION 5-3:
PTOTAL = PD (Pass Device) + PD (Bias) For the MCP1701, the internal quiescent bias current is so low (2 A, typ.) that the PD (bias) term of the power dissipation equation can be ignored. The maximum power dissipation can be estimated by using the maximum input voltage and the minimum output voltage to obtain a maximum voltage differential between input and output. The next step would be to multiply the maximum voltage differential by the maximum output current.
T J = 116.0 milliwatts x 52C/W + 55C T J = 61C
EQUATION 5-4:
PD = (VINMAX - VOUTMIN) x IOUTMAX Given: VIN VOUT IOUT TAMAX PMAX PMAX = = = = = = 3.3V to 4.1V 3.0V 2% 1 mA to 100 mA 55C (4.1V - (3.0V x 0.98)) x 100 mA 116.0 milliwatts

Note the following details of the code protection feature on Microchip devices: * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."
