■GENERAL
DESCRIPTION
ETR0356-003
Low Power Consumption, High Speed 200mA LDO Regulator - 10.5V Input
Even the XC6505 series is a low power consumption such as 5.5μA, the IC is a high speed CMOS LDO regulator that
features high accurate, low noise, high ripple rejection, and low dropout.
The series consists of a voltage reference, an error
amplifier, a driver transistor, a current limiter, a phase compensation circuit and a thermal shutdown 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 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 and the thermal shutdown circuit are built-in. These two protection circuits will operate
when the output current reaches current limit level or the junction temperature reaches temperature detection level.
