SNVS095F – MAY 2004 – REVISED MARCH 2015 LP295x Adjustable Micropower Low-Dropout Voltage Regulators
1 Features 3 Description The LP2952 and LP2953 are micropower voltage
regulators with very low quiescent current (130 ОјA
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. 1 2.3-V to 30-V Input Voltage Range
