GENERAL DESCRIPTION
The XC6221 series are precise, low noise, high speed, low dropout regulators. They are fabricated using Torex's CMOS process. Performance features of the series include high ripple rejection and low dropout voltage, and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit. The CE function enables the circuit to be in stand-by mode by inputing L level signal. In the stand-by mode, the series enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge resistance, and as a result the VOUT pin quickly returns to the VSS level. The series' output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. Output voltage is selectable in 50mV increments within a range of 0.8V~4.0V, using laser trimming technologies. The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin. The series achieves a great response with only 25A of low power consumption. Also the series has low dropout voltage characteristics, which is 80mA at IOUT=100mA and VOUT(T)=3.0V. With the use of ultra small package, USP-4 package, a small footprint circuit can be designed.

OPERATIONAL EXPLANATION
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal.
With the XC6221 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation circuit is built-in. Values required for the phase compensation are as the chart below. In order to ensure the stable phase compensation while avoiding run-out of values, please use the capacitor, which does not depend on bias or temperature too much. For a stable power input, please connect an input capacitor (CIN) of 1.0F between the VIN pin and the VSS pin.
SETTING OUTPUT VOLTAGE (V) 0.8 ~ 1.15 1.2 ~ 1.35 1.4 ~ 4.0 OUTPUT CAPACITOR VALUE CL=4.7uF CL=2.2uF CL=1.0uF
XC6221B series can discharge the electric charge in the output capacitor (CL), when a low signal to the CE pin, which enables a whole IC circuit turn off, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is set at 780(VOUT=4.0V @ VIN=6.0V at typical). The discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [Rdischg] and an output capacitor value (CL) as (=C x Rdischg), the output voltage after discharge via the N-channel transistor is calculated by the following formulas. V = VOUT(E) x e -t/, or t=In ( V / VOUT(E) ) ( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time, : CL auto-discharge resistance RdischgxOutput capacitor (CL) value C)

XC6221 Series
OPERATIONAL EXPLANATION (Continued)
The XC6221 series' foldback circuit operates as an output current limiter and a short protection of the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is shorted to the VSS level, a current of about 30mA flows. The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6221 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6221B series, the CL auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level becomes short. The output voltage becomes unstable, when the CE pin is open. If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input.
NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
