SS8061G
1A Low Dropout Regulator with Enable
FEATURES
DESCRIPTION
Adjustable output from 1.2V to 4.8V
Output voltage options 1.5V, 1.8V and 2.5V
(externally adjustable using resistors)
The SS8061 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 1 Amps. Since it has
Over-current and over-temperature protection
Dropout voltage of 400mV at 1A load
Enable pin
Quiescent current of 10µA in shutdown
SOT-89-5 Package
superior dropout characteristics compared to regular
LDOs, it can be used to supply 2.5V on motherboards
or 1.5V, 1.8V on peripheral cards from the 3.3V supply
thus allowing the elimination of costly heatsinks. An
enable-pin further reduces power dissipation while in
shut-down. The SS8061 provides excellent regulation
over variations in line, load and temperature.
APPLICATIONS
Battery-powered systems
Motherboards
Peripheral cards
Network cards
The SS8061 is available with 1.5V, 1.8V and 2.5V
internally preset outputs that are also adjustable using
external resistors.
