A1084
5A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR
THERMAL SHUTDOWN AND CURRENT LIMIT FUNCTIONS
DESCRIPTION
The A1084 is a series of low dropout three terminal
regulators with a dropout of 1.4V at 5A load current.
FEATURES
Provide Fixed Version and an Adjustable
Version, Output Value can be customized on
command.
Other than a fixed version (VOUT = 1.8V, 2.5V, 3.3V,
5V), The A1084 has an adjustable version, which
can set the output voltage with two external
resistors.
Maximum Output Current: 5A
Range of Operation Input Voltage: Max 15V
Line Regulation: 0.2% (Typ.)
Load Regulation: 0.2% (Typ.)
Environment Temperature: 0oC to +80oC
The A1084 offers thermal shutdown and current limit
functions, to assure the stability of chip and power
system.
Available in TO-252, TO-263-2 and TO-263-3
