XC6224 Series
150mA High Speed LDO Voltage Regulator with ON/OFF Switch
www.DataSheet4U.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.

NOTE:
*1: Unless otherwise specified, input voltage conditions are;
0.80V≦VOUT(T)≦2.60V ： {VIN=VOUT(T)+1.0V}
2.65V≦VOUT(T)≦2.80V ： {VIN=3.3V}
2.85V≦VOUT(T)≦3.00V ： {VIN=3.5V}
*2: VOUT(T): Nominal output voltage
*3: VOUT(E): Effective output voltage
This output voltages are measured at the constant current when the input voltages are stable as Note 1.
*4: Vdif＝{VIN1{*5}－VOUT1{*6}}
*5: VIN1=The input voltage when VOUT1 appears as input voltage is gradually decreased.
*6: VOUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VOUT(T)+1.0V} is input
*7: VOUT(T) ±20mV is the specification value of output voltage where VOUT(T) ≦1.20V.
