CS5203 Datasheet, PDF (1/6 Pages) First Components International – 3 Amp Low Dropout Postitive Voltage Regulator

CS-5203 3 Amp Low _{Dropout Postitive Voltage Regulator}
DESCRIPTION
00000The CS5203 series of positive adjustable
and fixed regulators are designed to provide 3A
with higher efficiency than in devices currently
available. All internal circuitry is designed to
operate down to 700 mV input to output
differential and the dropout voltage is fully
specified as a function of load current.
Dropout voltage of the device is 100 mV at
light loads and rising to 700 mv at maximum
output current. A second low current input is
required to achieve this dropout. The CS5203
can also be used as a single supply device
(3 pin version).
