1.5A, LOW DROPOUT

REGULATOR



DESCRIPTION

The UTC LR2915 is CMOS-based positive voltage and a very

low dropout regulator IC that minimum input voltage is 2.5V and is

capable of delivering the continuous output load current up to 1.5A.

It has features of low dropout (maximum 300mV at 1A), a very

low quiescent current (typically 300uA at 0.1A).

external resistor divider and it has ±2% accuracy through all

temperature ranges include the line as well as load variations. It is

allowed to use a small 4.7μF MLCC input and output capacitor to

deliver the current with the stable operation.

Built-in Soft-Start function reduces the inrush current and the

other features are include over current protection (OCP),

short-circuit protection (SCP), and thermal shut down protection

(TSD).
