The Texas Instruments LP3985 is a precision low-dropout linear regulator delivering a fixed 5.0V output at up to 150mA. Its ultra-low 150µA quiescent current and 0.1V dropout voltage make it exceptionally efficient for battery-powered applications. The device offers excellent power supply rejection (50dB at 1kHz) and comes in a compact 5-DSBGA package, ideal for space-constrained designs.
- Extended Battery Life: Ultra-low 150µA quiescent current minimizes standby power consumption in portable devices.
- High Efficiency at Low Dropout: Only 0.1V dropout at 150mA allows operation close to the battery's end-of-life voltage.
- Clean Power Delivery: 50dB PSRR at 1kHz filters out supply noise for sensitive analog and RF circuits.
- Space-Saving Package: The 5-DSBGA (1.41x1.08mm) footprint is ideal for miniaturized designs.
Portable Battery-Powered Devices
The LP3985's low 150µA quiescent current and 150mA output make it ideal for extending battery life in wearables, hearing aids, and remote sensors where every microamp matters.
Noise-Sensitive Analog Circuits
With PSRR of 50dB at 1kHz and 40dB at 10kHz, this LDO effectively filters power supply noise for precision analog-to-digital converters and operational amplifiers in instrumentation.
Wireless Communication Modules
The stable 5.0V output and low dropout of 0.1V ensure reliable operation for RF transceivers and Bluetooth modules, maintaining signal integrity even as battery voltage sags.
Microcontroller Power Supplies
Provide clean, regulated 5.0V to MCUs and digital logic, with the tiny 5-DSBGA package saving valuable board space in compact IoT designs.
Sensor Conditioning Circuits
The low noise and high PSRR characteristics make it suitable for powering bridge sensors and signal conditioning amplifiers in industrial and medical applications.
Audio Equipment
Use the LP3985 to power audio codecs and amplifiers, where the 50dB PSRR at 1kHz helps minimize hum and interference from digital circuits.
