XC6224
Series
1.2V Low Voltage Operation,150mA High Speed LDO Voltage Regulator
ETR0340-008
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 (C
L
) 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 C
L
to be discharged via the internal switch, and as a result the V
OUT
pin
quickly returns to the V
SS
level.
The over current protection circuit is integrated and operates when the output current reaches current limit level.
