The LP2950 and LP2951 devices are bipolar, low-dropout voltage regulators that can
accommodate a wide input supply-voltage range of up to 30 V. The easy-to-use, 3-pin LP2950 is
available in fixed-output voltages of 5 V, 3.3 V, and 3 V. However, the 8-pin LP2951 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 LP2951 outputs a
fixed 5 V, 3.3 V, or 3 V (depending on the version). Alternatively, by leaving the SENSE and
VTAP pins open and connecting FEEDBACK to an external resistor divider, the
output can be set to any value between 1.235 V to 30 V.
