Dual Output 300mA LDO

Linear Regulator

POWER MANAGEMENT

Features

Description

The SC563 is a dual output, low dropout linear voltage

regulator designed for use in battery powered applica-

tions and other applications with space constraints and

low power requirements. The SC563 provides ﬁxed output

voltages up to 300mA of load current per channel. Fixed

output voltages for each output eliminates the need for

external feedback resistors.



Input voltage range — 2.3V to 5.5V

Two 300mA (maximum) outputs

Dropout at 300mA load — ꢀ80mV (Typ)

Quiescent supply current — 50μA (x2)

Shutdown current — ꢀ00nA

Output noise — ꢀ00μV_RMS/V

Over-temperature protection

Short-circuit protection

Under-voltage lockout

The device has separate input, output and enable pins for

each LDO channel. Using the lowest possible input

voltage for each output voltage reduces the power loss

for each rail. This improves overall package thermal per-

formance and eﬃciency compared to single input voltage

devices.

Applications



Consumer electronics

Wearable & Portable electronics

Cell phones

The device has fast turn-on and turn-oﬀ voltage slew rate

for fast system start up and reset response. Low quiescent

current extends battery life.

GPS devices

Set top boxes/HDTVs

Communication electronics

Industrial electronics

The SC563 family of devices provide protection circuitry

such as short-circuit protection, under-voltage lockout,

and thermal protection to prevent device failures. Stability

is maintained by using ꢀµF capacitors on the output pins.

The MLPD-UT8 ꢀ.6mmxꢀ.2mm package and small ceramic

bypass capacitors minimize the required PCB area.
