The LP3985ITL-3.0/NOPB is a precision 3.0V low dropout linear regulator from Texas Instruments, capable of delivering 150mA of output current. Its ultra-low 0.1V dropout voltage and 150µA quiescent current make it an efficient choice for battery-operated systems. Housed in a compact 5-DSBGA package, this LDO provides excellent PSRR of 50dB at 1kHz, ensuring clean power delivery for sensitive analog and RF circuits.
- Extended Battery Life: Ultra-low 0.1V dropout at 150mA allows operation down to 3.1V input, extracting more energy from batteries.
- Compact Footprint: The 5-DSBGA (1.41x1.08mm) package saves critical board space in miniaturized designs.
- Clean Output: 50dB PSRR at 1kHz suppresses high-frequency noise from switching regulators.
- Low Quiescent Current: 150µA ground current improves efficiency in always-on applications.
Battery-Powered Portable Devices
The low 0.1V dropout at 150mA maximizes battery life by allowing operation close to the battery's end-of-discharge voltage. The 150µA quiescent current further reduces standby power consumption in handheld instruments.
Precision Analog Reference Supplies
With 50dB to 40dB PSRR from 1kHz to 10kHz, this LDO effectively filters switching noise from upstream DC-DC converters, providing a clean supply for op-amps and ADCs in sensor signal chains.
Wireless Module Power
The 3.0V fixed output is ideal for powering RF transceivers and Bluetooth modules that require a stable 3V rail. The tiny 5-DSBGA package minimizes PCB area in space-constrained IoT designs.
Audio Codec Supplies
Low output noise and good line transient response make this regulator suitable for powering audio codecs and DACs, preventing audible artifacts caused by supply ripple.
Wearable Health Monitors
The ultra-small footprint and low quiescent current support continuous operation in fitness trackers and medical patches, where battery life and size are critical constraints.
Industrial Sensor Interfaces
Stable 3.0V output with 150mA capability powers digital isolators and level shifters in industrial field transmitters, ensuring reliable communication over long cable runs.
