The LP5900TLX-2.85 is a low dropout linear regulator from National Semiconductor, delivering a fixed 2.85V output with up to 150mA of current. Its ultra-low 50 µA quiescent current and high PSRR of 85dB make it an excellent choice for noise-sensitive, battery-powered applications. Housed in a compact 4-DSBGA package, this LDO is designed for space-constrained portable electronics.
- Extended Battery Life: Ultra-low 50 µA quiescent current minimizes power draw in standby mode.
- Clean Power Delivery: High PSRR (85dB at 100Hz) filters supply noise for sensitive analog and RF circuits.
- Space-Saving Design: The 1x1mm 4-DSBGA package is ideal for miniaturized wearable and IoT devices.
- Low Dropout: 0.15V dropout at 150mA allows operation close to the battery's end-of-life voltage.
Portable Battery-Powered Devices
With a low quiescent current of 50 µA and a tiny 1x1mm DSBGA package, the LP5900TLX-2.85 is ideal for extending battery life in wearables, hearing aids, and IoT sensors where space is at a premium.
Precision Analog Circuits
The high PSRR of 85dB at 100Hz ensures clean, stable power for sensitive analog-to-digital converters (ADCs) and operational amplifiers, minimizing noise-induced errors in measurement systems.
RF Transceivers and Wireless Modules
Excellent noise rejection up to 100kHz helps maintain signal integrity in RF transceivers, Bluetooth modules, and Zigbee devices, preventing power supply noise from degrading wireless performance.
Low-Power Microcontrollers
Supplying a stable 2.85V rail to low-power MCUs ensures reliable operation during sleep and active modes, with the low dropout voltage maximizing efficiency as the battery discharges.
Medical Implantable Devices
The ultra-small footprint and low power consumption make this regulator suitable for implantable sensors and stimulators where size and battery longevity are critical constraints.
