Preliminary
LINEAR INTEGRATED CIRCUIT
1.5A ULTRA LOW DROPOUT
LINEAR REGULATOR WITH
PROGRAMMABLE
SOFT-START
 DESCRIPTION
The UTC L1803 is a typical LDO that features a
user-programmable soft-start, very low dropout voltage as low as
0.15V at output current 1.5A, an enable input and a power-good
output.
The soft-start reduces inrush current of the load capacitors and
minimizes stress on the input power source during start-up. An
enable pin to further reduce power dissipation while shutdown. And
power-good output indicates the output voltage status.
The UTC L1803 is stable with any type of output capacitor of
2.2µF or more. A precision reference and feedback control deliver
2% accuracy over load, line, and operating temperature ranges.
 FEATURES
