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
to 3.3V with 0.1V per step 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, TO-252 and
external resistors to set the output voltage ranges from
0.8V to 4.5V.

... RT9183 Adjustable Operation The adjustable version of the RT9183 has an output voltage range of 0.8V to 4.5V. The output voltage is set by the ratio of two external resistors as shown in Figure 2. The value of R2 should be less than 80k to maintain regulation. In critical applications, small voltage drop is caused by the resistance (R ...
