The Texas Instruments LP5900TLX-3.3/NOPB is a 150mA low-dropout linear regulator delivering a fixed 3.3V output. Its ultra-low 50µA quiescent current and high PSRR (85dB at 100Hz) make it ideal for battery-powered and noise-sensitive applications. The 1x1mm DSBGA package enables compact designs in portable electronics.
- Extended Battery Life: 50µA quiescent current minimizes standby power draw in portable devices.
- Clean Power Delivery: 85dB PSRR at 100Hz effectively filters input ripple for sensitive analog circuits.
- Space-Saving Footprint: 1x1mm DSBGA package reduces PCB area by up to 70% vs. SOT-23 alternatives.
- Low Dropout: 150mV dropout at full load supports operation from nearly depleted batteries.
Battery-Powered IoT Sensors
The 3.3V fixed output and 50µA quiescent current make it ideal for always-on IoT 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 monitors and pulse oximeters, reducing noise-induced measurement errors.
Wearable Electronics
The ultra-compact 1x1mm DSBGA package fits space-constrained smartwatch and fitness tracker PCBs while delivering 150mA for MCU and Bluetooth LE subsystems.
Noise-Sensitive Audio Codecs
High PSRR across 100Hz-100kHz suppresses power supply ripple from switching converters, ensuring high-fidelity audio performance in portable speakers and headphones.
Industrial Sensor Interfaces
Stable 3.3V rail with low dropout supports 4-20mA loop-powered transmitters and industrial pressure sensors operating from 3.6V battery packs.
RF Transceiver Power
Low noise and fast transient response maintain RF signal integrity in 2.4GHz transceivers, preventing spurious emissions during transmit bursts.
