LP2954 Overview
The LP2954 is a 5-V micropower LDO with very low quiescent current (90 μA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light loads and 470 mV at 250-mA load current). The quiescent current increases only slightly at dropout (120 μA typical), which prolongs battery life. The LP2954 with a fixed 5-V output is available in three-pin TO-220 and DDPAK/TO-263 packages.
