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
mVRMS. 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.
