CS5205 Datasheet, PDF (1/7 Pages) First Components International – 5A Low Dropout Positive Voltage Regulator

CS-5205 5A Low Dropout Positive Voltage Regulator
DESCRIPTION
00000The CS-5205 series of positive adjustable
and fixed regulators are designed to provide 5A
with higher efficiency than currently available
devices. All internal circuitry is designed to
operate down to 500 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 500 mV at maximum
output current. A second low current input is
required to achieve this dropout. The CS5205
can also be used as single supply device
(3 pin version). On-chip trimming adjusts the
reference voltage to 1%. Current limit is also
trimmed, minimizing the stress on both the
regulator and power source circuitry under
overload conditions.0000000000000000000000
00000The CS-5205 series are ideal to power the next
generation of advanced microprocessor on mother-
bords where both 5V and 3.3Vsupplies are available.
