L1127
Preliminary
ULTRA-LOW-NOISE,
HIGH-SPEED, LOW-DROPOUT,
300mA LINEAR REGULATOR
CMOS IC
„ DESCRIPTION
As a low dropout linear regulator, the UTC L1127 only needs low
input voltage (2.5~6V), and can deliver current to 300mA for setting
the output voltage.
The UTC L1127 is ideal for being used in such battery-powered
equipments notebook, personal computer and mother board. Its
typical dropout voltage is 200mV at loading current 300mA.
L1127 has 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.3V, 4.2V, 4.75V,
fixed voltage versions and 0.8V to 5.5V adjustable voltage versions.
To protect itself against current over-loads and over temperature,
the L1127 has short current limit and thermal shutdown functions.
