DESCRIPTION
The SC1563 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 500 milliamps. Since
it has superior dropout characteristics compared to
regular LDOs, it can be used to supply 2.5V on
motherboards or 2.8V on peripheral cards from the
3.3V supply with no heatsink. Additionally, the SC1563
has a shutdown pin, to further reduce power
dissipation while shut down. The SC1563 provides
excellent regulation over variations in line, load and
temperature.
The SC1563 is available as a five terminal fixed or
adjustable output voltage device with enable. The
device is available in a 5-pin SOT-23 package and an
8-pin MSOP package for higher power dissipation/
lower junction temperature.
FEATURES
= 450mV dropout @ 500mA
= Designed to operate with ceramic capacitors
= Adjustable output from 1.200V to 3.3V
= Multiple output voltage options (all parts also
adjustable externally using resistors)
= Over current and over temperature protection
= Enable pin
= 1µA quiescent current in shutdown
= Low reverse leakage (output to input)
= Full industrial temperature range
APPLICATIONS
= Battery powered systems
= Motherboards
= Peripheral cards
= PCMCIA cards

NOTES:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) Defined as the input to output differential at which the output voltage drops to 1% below the value measured at
a differential of 0.7V.
(3) Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this requirement.
Adjustable versions only.
(4) Guaranteed by design.
(5) When VADJ exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the
error amplifier and connects VADJ instead.
