Dual Output 300mA LDO
Linear Regulator
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.
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.
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.
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 1µF capacitors on the output pins.
The MLPD-UT8 1.6mmx1.2mm package and small ceramic
bypass capacitors minimize the required PCB area.
