L1127 Datasheet
ULTRA-LOW-NOISE, HIGH-SPEED, LOW-DROPOUT, 300mA LINEAR REGULATOR
 
 
 
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, 5.2V
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.
