NCV8623
NCP623, NCV8623
Voltage Regulator - Low
Dropout, Ultra Low Noise
150 mA
The NCP623/NCV8623 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. 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 shortcircuit
protection provide for a robust system design.
