XC6227
Series
700mA High Speed LDO Regulator with Reverse Current Protection
ETR0354-003
■GENERAL
DESCRIPTION
The XC6227 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed
voltage regulator.
The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection circuit, a
reverse current protection circuit and a phase compensation circuit.
The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin.
Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output
current reaches the current limit level or junction temperature reaches the temperature limit. With the reverse current protection
function of a driver transistor, the reverse current flow is prohibited when V
OUT
voltage is higher than V
IN
voltage. For an example,
when a battery is connected to the V
OUT
pin, battery current will not flow back to the XC6227.

■PIN
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 VSS (No. 5) pin.
