NCP623
Ultra Low Noise
150 mA Low Dropout
Voltage Regulator with
ON/OFF Control
The NCP623 low dropout linear regulator can deliver up to 150 mA
of output current with a typical dropout voltage of 180 mV. This low
dropout feature helps to maintain a regulated output voltage for a
longer period of time as the lifetime of the battery decreases.
It is the ideal choice for noise sensitive environments like portable
applications where noise performance and space are at a premium. The
typical output noise voltage specification is 25 V
RMS
. The space
saving package choices include a Micro8
or DFN6. An additional
noise saving feature of this device is its ability to filter choppy signals
on the power supply by providing a typical DC ripple rejection of
90 dB and
70 dB at 1.0 kHz.
The NCP623 is designed to work with very low ESR capacitors such
as ceramic capacitors which are common in the industry now.
Additional features such as thermal shutdown and short
circuit
protection provide for a robust system design.
