NCP4688
150 mA, Low Noise, LDO
Linear Voltage Regulator
The NCP4688 is a CMOS 150 mA LDO linear voltage regulator
with high output voltage accuracy which features a low noise output
voltage and high ripple rejection. The low level of output noise
10 mVrms typically is kept at any output voltage. The very common
SOT23−5 package and small mDFN 1x1 package are suitable for
industrial applications, portable communication equipments and RF
modules.
Features
• Operating Input Voltage Range: 2 V to 5.25 V
• Output Voltage Range: 1.2 to 4.8 V (available in 0.1 V steps)
• ±1% Output Voltage Accuracy
• Output Noise: 10 mVrms
• Line Regulation: 0.02%/V
• Current Limit Circuit
• High PSRR: 80 dB at 1 kHz, 75 dB at 10 kHz
• Available in SOT−23−5 and mDFN 1.0 x 1.0 mm Package
• These are Pb−Free Devices
Typical Applications
• Home Appliances, Industrial Equipment
• Cable Boxes, Satellite Receivers, Entertainment Systems
• Car Audio Equipment, Navigation Systems
• Notebook Adaptors, LCD TVs, Cordless Phones and Private LAN
Systems
• RF Modules
