AZ1117
1A LOW DROPOUT LINEAR REGULATOR
Description
The AZ1117 is a series of low dropout three-terminal regulators with a
dropout of 1.15V at 1A output current.
The AZ1117 series provides current limiting and thermal shutdown.
Its circuit includes a trimmed bandgap reference to assure output
voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V,
5.0V and adjustable versions or 2% for 1.2V version. Current limit is
trimmed to ensure specified output current and controlled short-circuit
current. On-chip thermal shutdown provides protection against any
combination of overload and ambient temperature that would create
excessive junction temperature.
The AZ1117 has an adjustable version, which can provide the output
voltage from 1.25V to 12V with only 2 external resistors.
The AZ1117 series is available in the industry standard SOT223,
SOT89, TO220-3, TO252-2 (3), TO252-2 (4), TO252-2 (5) and TO263
power packages.
