The LP2981AIM5-3.6/NOPB from Texas Instruments is a fixed 3.6V LDO regulator delivering 100mA. With a low dropout of 0.37V at full load and a quiescent current of just 95µA, it is optimized for battery-powered and noise-sensitive applications. The SOT-23-5 package enables compact designs.
- Ultra-low quiescent current (95µA) maximizes battery life.
- Low dropout (0.37V @ 100mA) supports low input margins.
- High PSRR (63dB @ 1kHz) for clean audio and RF supplies.
- Small SOT-23-5 package for space-constrained designs.
Battery-Powered Instruments
95µA quiescent current and 100mA output are ideal for portable meters and handheld tools.
Memory Supply (RTC/CMOS)
3.6V output suits backup power for real-time clocks and SRAM.
Wireless Sensors
Low dropout (0.37V) allows operation from a 3.7V Li-ion battery down to 3.97V input.
Audio Codec Power
63dB PSRR at 1kHz reduces mid-frequency noise for audio clarity.
Wearable Devices
Compact SOT-23-5 package fits tight PCB layouts in smartwatches and fitness bands.
Reference Voltage Source
Stable 3.6V output for precision analog references.
