CS-5201 Datasheet, PDF (1/6 Pages) First Components International – 1Amp Low Dropout Positive Voltage Regulator

CS-5201 1Amp Low Dropout Positive Voltage Regulator
DESCRIPTION
00000The CS5201 series of positive adjustable
and fixed regulators are designed to provide 1A
with higher efficiency than currently available
devices. 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 CS5201
can also be used as single supply device
(3 pin version).
