XC6420 Series
150mA Small Dual LDO Regulator with ON/OFF Switch
■GENERAL DESCRIPTION
The XC6420 series is a small dual CMOS LDO regulator with 2-channel 150mA outputs. The series features high speed,
high accuracy, high ripple rejection and low dropout voltage. The series is capable of high density board installation by the
small package of two low on-resistance regulators. Each output voltage is internally set in a range from 1.2V to 3.6V in
increments of 0.05V with ±2% accuracy.
The EN function controls the two regulators on/off independently. In the stand-by mode, the electric charge at the output
capacitor C
The series is also compatible with low ESR ceramic capacitors. The high level of output stability is maintained even during
frequent load fluctuations, due to the excellent transient response performance. The two regulators are completely isolated so
that a cross talk during load fluctuations is minimized.

● Portable game consoles
● Portable multimedia player
● Digital still cameras, Camcorders

■OPERATIONAL EXPLANATION
The voltage divided by resistors Rx1 & Rx2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET connected to the V
pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit
V
OUT
pin is then driven by the subsequent output signal. The output voltage at the
OUT
operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's
signal.
<Low ESR Capacitor>
The XC6420 needs an output capacitor (CL) for phase compensation. In order to ensure the effectiveness of the phase
compensation, we suggest that an output capacitor (C

capacitor C
<Current Limiter, Short-Circuit Protection>
The XC6420 includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the
current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit
operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage
drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows.
<EN Pin>
The IC's internal circuitry can be shutdown via the signal from the EN pin with the XC6420 series. In shutdown mode, the
series enables the electric charge at the output capacitor C

<CL Auto-Discharge Function>
XC6420 series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the EN pin,
which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the V
and the V

■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. 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.
3. Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on
output current. Please strengthen V
4. Please wire the input capacitor (CIN) and the output capacitor (CL) as short and close to the IC as possible.
