- LD3985M25R
Description
The LD3985xx is a low-dropout, low-noise voltage regulator that provides up to 150 mA of current from an input voltage range of 2.5 V to 6 V. It is designed to work with low ESR ceramic capacitors and features an ultra-low dropout voltage (60 mV typ. at 150 mA load, 0.4 mV typ. at 1 mA load), very low quiescent current (85 μA typ. at no load, 170 μA typ. at 150 mA load), and a fast turn-on time (typ. 200 μs). The LD3985xx also includes logic-controlled electronic shutdown, internal current and thermal limit, and output low noise voltage (30 μVRMS over 10 Hz to 100 kHz).
Features
