LP2952/LP2952A/LP2953/LP2953A Adjustable Micropower Low-Dropout Voltage Regulators
The LP2952 and LP2953 are micropower voltage regulators designed for battery-powered systems, featuring very low quiescent current (130 µA typical at 1 mA load) and low dropout voltage. These devices retain the desirable characteristics of the LP2951 while offering increased output current up to 250 mA, additional features, and an improved shutdown function with an internal crowbar.
| Output Voltage Range | 1.23V to 29V |
|---|---|
| Maximum Output Current | 250 mA |
| Typical Quiescent Current (1mA load) | 130 µA |
| Dropout Voltage (250 mA load) | 470 mV |
The typical quiescent current is 130 µA at a 1 mA load.
Available versions include 5V and 3.3V fixed voltages, as well as adjustable ranges.
Yes, reverse battery protection is provided by the internal circuitry.
