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 fe...
