GENERAL DESCRIPTION Mobilephone : 15107552758
The XC6228 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, a
phase compensation circuit.
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 output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.
The output voltage is selectable from 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.1V, 3.3V which fixed by laser trimming technologies.
The over current protection circuit is built-in. This protection circuit will operate when the output current reaches current limit
level.

NOTE:
Unless otherwise stated regarding input voltage conditions, VIN=VOUT(T)＋1.0V.
（*1）VOUT(E): Effective output voltage
(i.e. the output voltage when “VOUT(T)+1.0V” is provided at the VIN pin while maintaining a certain IOUT value.)
（*2）VOUT(T) : Nominal output voltage
（*3）Vdif＝VIN1－VOUT1 (VIN1≧1.6V)
VIN1=The input voltage when VOUT1 appears as input voltage is gradually decreased.
VOUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized VOUT(T)+1.0V is input for every IOUT.
