MIC5365/6
High Performance Single 150mA LDO
General Description
The MIC5365/6 is an advanced general purpose linear regulator offering high power supply rejection (PSRR) in an ultra-small 1mm x 1mm package. The MIC5366 includes an auto-discharge feature that is activated when the enable pin is low. The MIC5365/6 is capable of sourcing 150mA output current and offers high PSRR making it an ideal solution for any portable electronic application. Ideal for battery powered applications, the MIC5365/6 offers 2% initial accuracy, low dropout voltage (155mV @ 150mA), and low ground current (typically 29A). The MIC5365/6 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5365/6 is available in several advanced packages including a lead-free (RoHS compliant) 1mm x 1mm Thin (R) 2 MLF occupying only 1mm of PCB area, a 75% reduction in board area compared to SC-70 and 2mm x 2mm MLF(R) packages. It is also availabe in an SC-70-5 package. The MIC5365/6 has an operating junction temperature range of -40C to 125C. Data sheets and support documentation can be found on Micrel's web site at www.micrel.com.

Notes: 1. Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to function outside its operating rating. 3. The maximum allowable power dissipation of any TA (ambient temperature) is PD(max) = TJ(max) - TA) / JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. 4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. 5. Specification for packaged product only. 6. Regulation is measured at constant junction temperature using low duty cycle pulse testing, changes in output voltage due to heating effects are covered by the thermal regulation specification. 7. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. For outputs below 2.5V, dropout voltage is the input-to-output differential with the minimum input voltage 2.5V. 8. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current.

Application Information
MIC5365 and MIC5366 are Low noise 150mA LDOs. The MIC5366 includes an auto-discharge circuit that is switched on when the regulator is disabled through the Enable pin. The MIC5365/6 regulator is fully protected from damage due to fault conditions, offering linear current limiting and thermal shutdown. Input Capacitor The MIC5365/6 is a high-performance, high bandwidth device. An input capacitor of 1F is required from the input to ground to provide stability. Low-ESR ceramic capacitors provide optimal performance at a minimum of space. Additional high-frequency capacitors, such as small-valued NPO dielectric-type capacitors, help filter out high-frequency noise and are good practice in any RF-based circuit. X5R or X7R dielectrics are recommended for the input capacitor. Y5V dielectrics lose most of their capacitance over temperature and are therefore, not recommended. Output Capacitor The MIC5365/6 requires an output capacitor of 1F or greater to maintain stability. The design is optimized for use with low-ESR ceramic chip capacitors. High ESR capacitors are not recommended because they may cause high frequency oscillation. The output capacitor can be increased, but performance has been optimized for a 1F ceramic output capacitor and does not improve significantly with larger capacitance. X7R/X5R dielectric-type ceramic capacitors are recommended because of their temperature performance. X7R-type capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much as 50% and 60%, respectively, over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range. No-Load Stability Unlike many other voltage regulators, the MIC5365/6 will remain stable and in regulation with no load. This is especially important in CMOS RAM keep-alive applications.
Enable/Shutdown The MIC5365/6 comes with an active-high enable pin that allows the regulator to be disabled. Forcing the enable pin low disables the regulator and sends it into a "zero" off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage. The active-high enable pin uses CMOS technology and the enable pin cannot be left floating; a floating enable pin may cause an indeterminate state on the output. Thermal Considerations The MIC5365/6 is designed to provide 150mA of continuous current in a very small package. Maximum ambient operating temperature can be calculated based on the output current and the voltage drop across the part. For example if the input voltage is 3.6V, the output voltage is 2.8V, and the output current = 150mA. The actual power dissipation of the regulator circuit can be determined using the equation: PD = (VIN - VOUT1) I OUT + VIN IGND Because this device is CMOS and the ground current is typically <100A over the load range, the power dissipation contributed by the ground current is < 1% and can be ignored for this calculation. PD = (3.6V - 2.8V) x 150mA PD = 0.120W To determine the maximum ambient operating temperature of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation:
TJ(max) - TA PD(max) = JA
TJ(max) = 125C, the maximum junction temperature of the die, JA thermal resistance = 250C/W for the YMT package and 256.5C/W for the SC-70-5 package. Substituting PD for PD(max) and solving for the ambient operating temperature will give the maximum operating conditions for the regulator circuit. The junction-toambient thermal resistance for the minimum footprint is 250C/W. The maximum power dissipation must not be exceeded for proper operation.

Micrel, Inc. For example, when operating the MIC5365-2.8YMT at an input voltage of 3.6V and 150mA load with a minimum footprint layout, the maximum ambient operating temperature TA can be determined as follows: 0.120W = (125C - TA)/(250C/W) TA = 95C
MIC5365/6 Therefore the maximum ambient operating temperature of 95C is allowed in a 1mm x 1mm MLF(R) package. For a full discussion of heat sinking and thermal effects on voltage regulators, refer to the "Regulator Thermals" section of Micrel's Designing with Low-Dropout Voltage Regulators handbook.
