RT2515A
2A, Low Input Voltage, Ultra-Low Dropout Linear Regulator
with Enable
General Description
The RT2515A is a high performance positive voltage
regulator designed
for use in applications requiring ultra-
low input voltage and ultra-low dropout voltage at up to 2
amperes. It operates with an input voltage as low as 1.4V,
with output voltage programmable as low as
0.5V. The
RT2515A features ultra low dropout, ideal for applications
where output voltage is very close to input voltage.
Additionally, the RT2515A has an enable pin to further
reduce power dissipation while shutdown. The RT2515A
provides excellent regulation over variations in line, load
and temperature. The RT2515A is available in the SOP-8
(Exposed Pad) package. The output voltage can be set
by an external divider or fixed at 1.2V depending on how
the FB pin is configured.
