LP2951DG4 Description
The LP2951DG4 is a bipolar, low-dropout voltage regulator that can accommodate a wide input supply-voltage range of up to 30 V. The easy-to-use, 3-pin LP2951DG4 is available in fixed-output voltages of 5 V, 33 V, and 3 V. However, the 8-pin LP2951DG4 is able to output either a fixed or adjustable output from the same device. By tying the OUTPUT and SENSE pins together, and the FEEDBACK and VTAP pins together, the LP2951DG4 outputs a fixed 5 V, 3.3 V， or 3 V (depending on the version).
