Overview
The LP2985AIM5X-3.0/NOPB is a micropower, low-noise, ultra-low dropout (LDO) voltage regulator manufactured by Texas Instruments. Designed for applications requiring a stable and efficient power supply, this LDO regulator is housed in a compact SOT-23-5 package, making it suitable for space-constrained designs. With a fixed output voltage of 3.0 V and a maximum output current of 150 mA, it is ideal for portable electronics, IoT devices, and other low-power applications. Its low dropout voltage and high power supply rejection ratio (PSRR) ensure reliable performance even in noisy environments.
