NCP623/D
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 mV
RMS
. 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.
Features
• Very Low Quiescent Current 170 mA (ON, no load), 100 nA
(OFF, no load)
• Very Low Dropout Voltage, Typical Value is 137 mV at an Output
Current of 100 mA
• Very Low Noise with External Bypass Capacitor (10 nF),
Typically 25 mV
RMS
over 100 Hz to 100 kHz
• Internal Thermal Shutdown
• Extremely Tight Line Regulation Typically −90 dB
• Ripple Rejection −70 dB @ 1.0 kHz
• Line Transient Response: 1.0 mV for DV
in
= 3.0 V
• Extremely Tight Load Regulation, Typically 20 mV at DI
out
= 150 mA
• Multiple Output Voltages Available
• Logic Level ON/OFF Control (TTL−CMOS Compatible)
• Output Capacitor ESR Can Vary from 0 W to 3.0 W
• Pb−Free Packages are Available
Applications
• All Portable Systems, Battery Powered Systems, Cellular
Telephones, Radio Control Systems, Toys and Low Voltage Systems

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
*“C’’ (“case’’) is defined as the solder−attach interface between the center of the exposed pad on the bottom of the package, and the board to
which it is attached.
