XC6223
Series
■GENERAL
DESCRIPTION
ETR0339-009
Built-in Inrush Current Protection, 300mA High Speed LDO Voltage Regulator
The XC6223 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout
and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a
phase compensation circuit, a thermal shutdown circuit and an inrush current protection 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 output stabilization capacitor C
L
is also compatible with low ESR ceramic capacitors.
The output voltage is selectable in 0.05V increments within the range of 1.2V to 4.0V which fixed by laser trimming
technologies. 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 limit level.

CONFIGURATION
*The dissipation pad for the USPQ-4B03,USP-4 packages 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. 2) pin.

* Undefined state in XC6223 A/B/E/F/J/K/P/Q. On the other hand, Operation OFF states in XC6223C/D/G/H/M/N/R/T because
that an internal pull-down resister maintains the CE pin voltage to be low.
