XC6224 Series

150mA High Speed LDO Voltage Regulator with ON/OFF Switch

ETR0340-004

■GENERAL DESCRIPTION

The XC6224 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout

and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter,

and a phase compensation circuit.

This IC is suitable for a local power supply placed in adjacent to the system logic LSI or others, because of low input voltage

operation, using an ultra small package USPN-4B02 (0.75mm x 0.95mm) and stable operation with a small phase

compensation capacitor (CL) 0.47μF.

Also, this IC has fast transient response and high ripple rejection (70dB @ 1kHz).

The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series

enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin

quickly returns to the VSS level.

The over current protection circuit is integrated and operates when the output current reaches current limit level.
