LR1965
Preliminary
1.5A, LOW DROPOUT
REGULATOR WITH POWER
GOOD
CMOS IC
DESCRIPTION
The UTC LR1965 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) and very high
PSRR up to 86dB at 1A load current.
The output voltage can be set from 0.5V to (VIN - VDRP) with
an 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).
The UTC LR1965 is available in 8-SOP-EP package with
exposed pad for optimal power dissipation and 8-TDFN (3x3mm).
