NCP623  
Ultra Low Noise  
150 mA Low Dropout  
Voltage Regulator with  
ON/OFF Control  
http://onsemi.com  
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.

saving package choices include a Micro8or 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 shortcircuit  
protection provide for a robust system design.
