HPL1117

1A Low Dropout Fast Response Positive Adjustable Regulator and Fixed

1.8V, 2.5V, 2.85V, 3.3V and 5V

Features

General Description

The HPL1117 is a low dropout three-terminal adjust-

able regulators with 1A output current capability. In

order to obtain lower dropout voltage and faster tran-

sient response, which is critical for low voltage ap-

plications , the HPL1117 has been optimized. The

device is available in an adjustable version and fixed

output voltages of 1.8V, 2.5V, 2.85V, 3.3V and 5V.

The output available voltage range of an adjustable

version is from 1.25~10.7V with an input supply be-

low 12V. Dropout voltage is guaranteed at a maxi-

mum of 1.3V at 1A. Current limit is trimmed to ensure

specified output current and controlled short-circuit

current. On-chip thermal limiting provides protection

against any combination of overload that would cre-

ate excessive junction temperatures. The HPL1117

is available in the industry standard 3-pin TO-220, TO-

252, TO-263, and the low profile surface mount SOT-

223 power packages which can be used in applica-

tions where space is limited.
