Can Be Used for Fault Detection, Low-Input Line Detection, and so on. 2 Applications High-Efficiency Linear Regulator Regulator With Undervoltage Shutdown Low-Dropout Battery-Powered Regulator Snap-ON/Snap-OFF Regulator 3 Description The LP2952 and LP2953 are micropower voltage regulators with very low quiescent current (130 μA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light load and 470 mV at 250-mA load current). They are ideally suited for batterypowered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life. The LP2952 and LP2953 retain all the desirable characteristics of the LP2951, but offer increased output current, additional features, and an improved shutdown function. The automatic output discharge pul...
