XC6505
Series
■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.

CONFIGURATION
*The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking so as to
enhance mounting strength and heat release.
If the pad needs to be connected to other pins, it should be connected to the V
SS
(No. 5) pin.
