The LP3985IBPX-4.7 from National Semiconductor is a fixed 4.7V LDO delivering 150mA with an ultra-low dropout of 0.1V. Quiescent current is 165µA, and PSRR is 50dB at 1kHz. Packaged in 5-uSMD, it suits compact, high-performance designs.
- Ultra-Low Dropout: 0.1V at 150mA enables high efficiency with near-rail input.
- Good PSRR: 50dB at 1kHz reduces supply noise.
- High Current: 150mA supports moderate loads.
- Ultra-Small Package: 5-uSMD (0.93x1.11mm) for space-constrained designs.
High-Efficiency Portable Power
Ultra-low dropout of 0.1V at 150mA allows operation from a 4.8V battery with minimal power loss.
Noise-Sensitive Audio Circuits
PSRR of 50dB at 1kHz and 40dB at 10kHz reduces hum and interference in audio codecs.
Camera Modules
Stable 4.7V rail for image sensors and motor drivers in smartphones.
GPS Receivers
Clean supply for RF front-ends, improving signal acquisition sensitivity.
Industrial Sensors
150mA output powers 4-20mA loop transmitters with stable regulation.
Battery Management Systems
4.7V rail for monitoring ICs in multi-cell battery packs.
