The LP2980 is a 50 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. The LP2980 delivers unequaled performance in all specifications critical to battery-powered designs.
The LP2980 is a fixed‑output, 50 mA low‑dropout regulator designed for battery‑powered applications. It uses an optimized VIP™ process to achieve a typical dropout voltage of 120 mV at 50 mA load and a ground‑pin current of 375 pA.
The device is offered in 5.0 V, 3.3 V and 3.0 V versions, packaged in SOT‑23 or micro‑SMD formats, and requires only 1 µF of external output capacitance for stable operation. It operates from 2.1 V to 16 V input and includes over‑temperature and over‑current protection.
