LP2954 Datasheet (National Semiconductor) - 5V and Adjustable Micropower Low-Dropout Voltage Regulators

LP2954, 5V and Adjustable Micropower Low-Dropout Voltage Regulators

The LP2954 is a 5V micropower voltage regulator 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 batt
