The LP5900TLX-1.5/NOPB is a low-dropout linear regulator from National Semiconductor, delivering a fixed 1.5V output with up to 150mA of current. Its ultra-low 50µA quiescent current and high PSRR (85dB at 100Hz) make it an excellent choice for noise-sensitive, battery-powered applications. Housed in a compact 4-DSBGA package, this LDO balances performance and size for modern portable electronics.
- Extended Battery Life: Ultra-low 50µA quiescent current minimizes standby power draw in portable devices.
- Clean Power Delivery: High PSRR (85dB~40dB from 100Hz to 100kHz) suppresses input noise, ideal for analog and RF circuits.
- Space-Saving Design: The 4-DSBGA (1.01x1.29) package occupies minimal PCB area for compact product designs.
- Low Dropout: 0.15V dropout at 150mA allows operation close to the battery end-of-life voltage.
Battery-Powered IoT Sensors
The 50µA quiescent current and 1.5V output are ideal for always-on sensor nodes, extending battery life in wireless environmental monitoring.
Portable Medical Devices
With 85dB PSRR at 100Hz, this LDO provides clean, stable power for sensitive analog front-ends in glucose meters and pulse oximeters.
RF Transceivers
The high PSRR (85dB~40dB from 100Hz to 100kHz) minimizes noise coupling into RF circuits, ensuring reliable wireless communication in 1.5V logic systems.
Wearable Electronics
The ultra-small 4-DSBGA (1.01x1.29) package fits space-constrained smartwatch and fitness tracker PCBs while delivering 150mA for MCU and sensor loads.
Audio Codec Power
Low dropout (0.15V @ 150mA) maintains a stable 1.5V rail even as the battery discharges, reducing audio distortion in portable speakers.
Industrial Instrumentation
The low quiescent current and stable output make it suitable for precision 1.5V references in portable calibration equipment.
