The LP5951MF-1.3/NOPB from Texas Instruments is a fixed 1.3V low-dropout linear regulator delivering up to 150mA. Its ultra-low 55µA quiescent current and high PSRR (60dB at 100Hz) make it ideal for battery-powered and noise-sensitive applications. Housed in a compact SOT-23-5 package, it offers a dropout of just 0.35V at full load, ensuring efficient operation even with low input margins.
- Extended Battery Life: 55µA quiescent current minimizes standby drain in portable devices.
- Clean Output: 60dB PSRR at 100Hz rejects low-frequency ripple from switching converters.
- Low Dropout: 0.35V at 150mA allows operation from nearly depleted batteries.
- Compact Footprint: SOT-23-5 saves board space in space-constrained designs.
Battery-Powered IoT Sensors
The 55µA quiescent current and 1.3V output are ideal for extending battery life in always-on sensor nodes, where low standby power is critical.
Portable Medical Devices
With 60dB PSRR at 100Hz, this LDO effectively filters mains-related noise, ensuring clean power for sensitive analog front-ends in glucose meters or pulse oximeters.
RF Transceivers
The 50dB PSRR at 10kHz helps maintain stable voltage for RF oscillators and mixers, reducing spurious emissions and improving signal integrity.
Wearable Fitness Trackers
The SOT-23-5 package and 150mA capability support compact designs powering microcontrollers and Bluetooth LE modules from a single Li-ion cell.
Industrial Sensor Calibration
Stable 1.3V reference with low dropout ensures accurate ADC readings in temperature or pressure sensors operating near battery end-of-life.
Audio Codec Power
Low noise and high PSRR at audio frequencies make it suitable for powering codec analog supplies in portable audio devices.
