The Texas Instruments LP5900SDX-2.5/NOPB is a precision low-dropout linear regulator delivering a fixed 2.5V output at up to 150mA. Its ultra-low 50µA quiescent current and high PSRR (85dB at 100Hz) make it ideal for noise-sensitive portable and battery-powered applications. The 150mV dropout voltage at full load ensures efficient operation from low input voltages. Available in a compact 6-WSON package, this LDO provides stable, clean power for sensors, wireless modules, and precision analog circuits.
- Extended Battery Life: 50µA quiescent current minimizes standby drain, ideal for always-on devices.
- Excellent Noise Rejection: 85dB PSRR at 100Hz filters low-frequency ripple from switching regulators.
- Low Dropout Operation: 150mV dropout at 150mA allows use with nearly depleted batteries.
- Compact Footprint: 6-WSON (2.2x2.5mm) saves board space in wearables and IoT modules.
Battery-Powered IoT Sensors
The 50µA quiescent current and 150mA output make it ideal for always-on IoT sensors, extending battery life while providing clean 2.5V rail for MCUs and RF transceivers.
Portable Medical Devices
With 85dB PSRR at 100Hz, this LDO effectively rejects mains hum and low-frequency noise, ensuring stable operation for sensitive analog front-ends in glucose monitors or pulse oximeters.
Wireless Audio Modules
The low dropout of 150mV allows operation from a 2.7V Li-ion cell down to 2.65V, maximizing usable battery capacity for Bluetooth audio codecs requiring a quiet 2.5V supply.
Precision ADC Reference Supply
High PSRR across 100Hz-100kHz (85dB to 40dB) reduces switching noise from DC-DC converters, improving SNR for 16-bit ADCs in data acquisition systems.
Wearable Fitness Trackers
The compact 6-WSON package (2.2x2.5mm) fits space-constrained PCBs, while the 50µA quiescent current supports always-on step counters and heart-rate sensors.
Automotive Infotainment Backup
For RTC or microcontroller standby rails, the low quiescent current and stable 2.5V output ensure reliable memory retention during vehicle sleep modes.
