RT2516
2A, Low Input Voltage, Ultra-Low Dropout LDO Regulator
with Enable
General Description
The RT2516 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 RT2516
features ultra low dropout, ideal for applications where
output voltage is very close to input voltage. Additionally,
the RT2516 has an enable pin to further reduce power
dissipation while shutdown. The RT2516 provides
excellent regulation over variations in line, load and
temperature. The RT2516 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.
