NCP146
300 mA CMOS Low Dropout
Regulator
The NCP146 is 300 mA LDO that provides the engineer with a very
stable, accurate voltage with low noise suitable for space constrained,
noise sensitive applications. In order to optimize performance for
battery operated portable applications, the NCP146 employs the
dynamic quiescent current adjustment for very low I
Q
consumption at
no−load.
Features
• Operating Input Voltage Range: 1.7 V to 5.5 V
• Available in Fixed Voltage Options: 1.8 V
• Very Low Quiescent Current of Typ. 50 mA
• Low Dropout: 280 mV Typical at 300 mA
• ±1% Accuracy at Room Temperature
• High Power Supply Ripple Rejection: 75 dB at 1 kHz
• Thermal Shutdown and Current Limit Protections
• Stable with a 1 mF Ceramic Output Capacitor
• Available in SOIC−8 Package
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Typical Applicaitons
• Home Automation, Factory Automation
• Portable Medical Equipment
• Other Battery Powered Applications
