NCV8623
NCV8623 is Ultra Low Noise Voltage Regulator manufactured by onsemi.
NCP623, NCV8623
Voltage Regulator
- Low Dropout, Ultra Low Noise
150 m A
The NCP623/NCV8623 low dropout linear regulator can deliver up to 150 m A of output current with a typical dropout voltage of 180 m V. 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 m VRMS. 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 d B and
- 70 d B at 1.0 k Hz.
The NCP623 is designed to work with very low ESR capacitors such as ceramic capacitors which are mon in the industry now.
Additional Features such as thermal shutdown and short- circuit protection provide for a robust system design.
