XC6220
Series
1A LDO Voltage Regulator with “GreenOperation”
ETR0341-003
☆GreenOperation-Compatible
■GENERAL
DESCRIPTION
The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with
GreenOperation function. The series consists of a voltage reference, an error amplifier, a current limiter, an inrush current
prevention circuit and a phase compensation circuit plus a driver transistor.
With a 0.2Ω on-resistance driver transistor integrated and with output currents up to 1A, the ultra low dropout voltage
performance greatly extends battery life as does the GreenOperation function which can switch between high speed and
power save modes automatically.
Low ESR ceramic capacitors can be used for the output stabilization capacitor (C
L
).
Output voltage is selectable in 0.05V increments within the range of 0.8V~5.0V, using laser trimming technologies.
An over current protection circuit and a thermal shutdown circuit are built in. The over current protection circuit will operate
when the output current reaches its limit current. The thermal shutdown circuit will operate when the junction temperature
reaches its limit temperature. The inrush protection circuit works by controlling the inrush current which is charged to C
L
when
the IC starts up. In this way, any fluctuations to V
IN
caused by inrush current during system start up can be minimized.
The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power
consumption.

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.
