300mA High Speed LDO Regulator with ON/OFF Switch
■GENERAL DESCRIPTION
The XC6238 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.
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 VOUT pin
is also compatible with low ESR ceramic capacitors.
quickly returns to the VSS level. The output stabilization capacitor C
L
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 is built-in. This protection circuit will operate when the output current reaches
current limit level.

■OPERATIONAL EXPLANATION
XC6238D
XC6238H
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-
channel MOSFET which is connected to the VOUT pin is then driven by the subsequent output signal. The output voltage
at the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short circuit
protection operate in relation to the level of output current and heat dissipation. Further, the IC’s internal circuitry can be
<Low ESR Capacitor>
The XC6238 series needs an output capacitor CL for phase compensation. Please place an output capacitor (CL) at the output
pin (VOUT) and the ground pin (VSS) as close as possible. Please use the output capacitor (CL) is 1.0μF or larger. For a stable
power input, please connect an input capacitor (CIN) of 1.0μF between the VIN pin and the VSS pin.
<Current Limiter, Short-Circuit Protection>
The XC6238 has current limiter and droop shape of fold-back circuit. When the load current reaches the current limit, the
droop current limiter circuit operates and the output voltage drops. When the output voltage dropped, the fold-back circuit
operates and the output current goes to decrease. The output current finally falls at the level of 50mA when the output pin is
short-circuited.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin. In shutdown mode, the XC6238 series enables the
electric charge at the output capacitor (CL) to be discharged via the internal switch located between the VOUT and VSS pins,
and as a result the VOUT pin quickly returns to the VSS level. The XC6238 series has a pull-down resistor at the CE pin inside,
so that the CE pin input current flows.
<Inrush Current Protection>
The inrush current protection circuit is built in the XC6238H.

■NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings
be exceeded.
2. Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on output
current. Please strengthen VIN and VSS wiring in particular.
3. The input capacitor CIN and the output capacitor CL should be placed to the as close as possible with a shorter wiring.
4. The IC is controlled with constant current start-up. Start-up sequence control is requested to draw a load current after
even nominal output voltage rising up the output voltage.
5. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
