AZ1117E شرح
Preliminary Datasheet
1.0A LOW DROPOUT LINEAR REGULATOR
AZ1117E
General Description
The AZ1117E is a low dropout three-terminal
regulator with 1.0A output current ability, and the
dropout voltage is specified at typical 1.1V at 1.0A
current load, decreasing at lower load currents.
The AZ1117E has been optimized for low voltage
where transient response and minimum input voltage
are critical. It provides current limit and thermal
shutdown protection solutions. Its circuit includes a
trimmed band gap reference to assure output voltage
accuracy to be within ±1%. On-chip thermal
shutdown provides protection against a combination
of high current and ambient temperature that would
create excessive junction temperature.
The AZ1117E is available in 1.2V, 1.5V, 1.8V, 2.5V,
3.3V and 5.0V fixed output voltage versions and ADJ
output voltage version. The fixed versions integrate
the adjust resistors.
The AZ1117E is available in the industry-standard
TO-252-2 (3) and SOT-223 packages.
Features
