XC6220
Series
1A LDO Voltage Regulator with “Green Operation”
ETR0341-015
The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with
Green Operation 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, the ultra low dropout voltage performance with output currents up to 1A
greatly extends battery life as does the Green Operation function which can switch between high speed and power save modes
automatically. A low ESR ceramic capacitor 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 prevention circuit works by controlling the inrush current which charges to C
L
when
the IC starts up. In this way, voltage fluctuations in power supply 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.

* For the USP-6C, the No.5 and 6 V
IN
pins should be connected. The No.1
and 2 pins V
OUT
pins should be connected. The dissipation pad should be
solder-plated in reference 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. 4) pin.
* For the SOP-8FD, two power input pins (No.7 and No.8) output pins (No.1
and 2) should be connected. The dissipation pad should be solder-plated
in electrically open or connecting to the V
