LP2956A
Description
The LP2956 is a micropower voltage regulator with very low quiescent current (170 µA typical at light loads) and very low dropout voltage (typically 60 mV at 1 mA load current and 470 mV at 250 mA load current on the main output).
Key Features
- The auxiliary output is always on (regardless of main output status), so it can be used to power memory circuits
- Quiescent current increases only slightly at dropout, which prolongs battery life
- The error flag goes low if the main output voltage drops out of regulation
- Reverse battery protection is provi
