NCP623
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.
Features
- Very Low Quiescent Current 170 m A (ON, no load), 100 n A
(OFF, no load)
- Very Low Dropout Voltage, Typical Value is 137 m V at an Output
Current of 100 m A
- Very Low Noise with External Bypass Capacitor (10 n F),
Typically 25 m...
