LD501 Overview
The LD501 is an ultra-low noise, low dropout (LDO) linear regulator that operates from 2.2V to 5.5V and provides output current up to 150mA (LD501L), 200mA (LD501M), or 250mA (LD501P). The low dropout voltage 70mV at 150mA load (LD501L), 94mV at 200mA load (LD501M), or 118mV at 250mA load (LD501P), improves efficiency and allows operation over a wide input voltage range. The LD501 achieves ultra-low noise...
