■GENERAL DESCRIPTION

■FEATURES

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.

Output Current

Dropout Voltage

: 200mA <Up to 250mA (TYP.)>

: 80mV@ IOUT=100mA,

VOUT(T)=3.0V

Operating Voltage Range : 1.6V ~ 6.0V

Output Voltage

Setting Range

Accuracy

: 0.8V~4.0V (50mV increments)

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.

: +2% (VOUT >1.5V)

+30mV (VOUT≦1.45V)

Low Power Consumption: 25μA (TYP.)

Standby Current

: Less than 0.1μA

: 70dB @ 1kHz

High Ripple Rejection

Operating Temperature : -40℃~85℃

Range

Output voltage is selectable in 50mV increments within a range

of 0.8V~4.0V, using laser trimming technologies.

Low ESR Capacitor

: 1.0μF Ceramic capacitor

compatible

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 25μA of

low power consumption. Also the series has low dropout

voltage characteristics, which is 80mA at IOUT=100mA and

VOUT(T)=3.0V.

Ultra Small Packages

: USP-4, SOT-25, SSOT-24

With the use of ultra small package, USP-4 package, a small

footprint circuit can be designed.
