The LP2985AIM5X-2.8 from Texas Instruments is a micropower, low-noise, ultra-low-dropout linear regulator designed for use with very low ESR output capacitors. It delivers up to 150 mA of output current with an input voltage range of 2.5 V to 16 V.
This regulator provides a fixed 2.8V output voltage with an accuracy of ±1% for the A grade. It features an ultra-low dropout voltage, typically 300 mV at 150 mA, and a quiescent current of only 75 µA at a 1 mA load, reducing power consumption in battery-operated devices. The device also offers low ground pin current across all load conditions.
Key electrical characteristics include a PSRR of 45 dB at 1 kHz and low output noise of 30 µVRMS when a 10 nF bypass capacitor is used. Protection features include overcurrent, overtemperature, and short-circuit protection. The LP2985AIM5X-2.8 operates within a junction temperature range of -40°C to 125°C.
Packaged in a 5-pin SOT-23-5 (SC-74A, SOT-753) surface-mount package, this regulator requires minimal external components and is stable with low-ESR output capacitors like 2.2 µF ceramic types. Its compact size and low power consumption make it ideal for portable electronics.
