RT2515H
2A, Low Input Voltage, Ultra-Low Dropout LDO Regulator
with Enable
General Description
Features
z Input Voltage as Low as 1.4V
z Ultra-Low Dropout Voltage 400mV @ 2A
z Over Current Protection
The RT2515H 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
RT2515H features ultra low dropout, ideal for applications
where output voltage is very close to input voltage.
Additionally, the RT2515H has an enable pin to further
reduce power dissipation while shutdown. The RT2515H
provides excellent regulation over variations in line, load
and temperature. The RT2515H is available in the SOP-8
(Exposed Pad) package. The output voltage can be set
by an external divider depending on how the FB pin is
configured.
