## Description
The LP2950 and LP2951 are bipolar, low-dropout voltage regulators accommodating input voltages up to 30V. The LP2950 is a 3-pin device with fixed 5V, 3.3V, and 3V outputs. The LP2951 is an 8-pin device offering fixed or adjustable outputs. The 8-pin version can be set to a fixed 5V, 3.3V, or 3V by tying pins, or adjusted to any voltage between 1.235V and 30V using an external resistor divider.

The LP2951 includes a shutdown feature and supervisor reset function that triggers when output drops by 6% of nominal.
