XC6224 Series 150mA High Speed LDO Voltage Regulator with ON/OFF Switch www.

com 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.
47 F.
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.
