RT9183H-33PG Overview

Ultra Low Dropout 1.5A Linear Regulator

RT9183
Ultra Low Dropout 1.5A Linear Regulator
General Description
The RT9183 series are high performance linear voltage
regulators that provide ultra low-dropout voltage, high output
current with low ground current. It operates from an input
of 2.3V to 5.5V and provides output current up to 1.5A
thus is suitable to drive digital circuits requiring low voltage
at high currents.
The RT9183 has superior regulation over variations in line
and load. Also it provides fast respond to step changes in
load. Other features include over-current and over-
temperature protection. The adjustable version has enable
pin to reduce power consumption in shutdown mode.
The devices are available in fixed output voltages
of 1.2V,
1.8V, 2.5V, 3.3V and as an adjustable device with a 0.8V
reference voltage. The RT9183 regulators are available in
3-lead SOT-223 and TO-263 packages (fixed output only
for the 3-lead option). Also available are 5-lead TO-263
and fused SOP-8 packages with two external resistors to
set the output voltage ranges from 0.8V to 4.5V.
