UTC1117 Datasheet, PDF (1/7 Pages) Hangzhou Youwang Electronics Co., Ltd – LOW DROPOUT POSITIVE VOLTAGE REGULATOR

UTC1117
LINEAR INTEGRATED CIRCUIT
1A LOW DROPOUT POSITIVE
VOLTAGE REGULATOR
DESCRIPTION
The UTC1117 is a 1A low-dropout positive voltage regulator.
It is available in fixed and adjustable output voltage versions.
Over-current and thermal protection are integrated onto the
chip. Output current will decrease while it reaches the pre-set
current or temperature limit. The dropout voltage is specified at
1.2V Maximum at full rated output current. UTC1117 Series
provides excellent regulation over line, load and temperature
variations.
