Texas Instruments LP2951-33-Q1
The LP2951-xx-Q1 devices are bipolar, low-dropout voltage regulators that can accommodate a wide input supply-voltage range of up to 35 V. The 8-pin LP2951-xx-Q1 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-xxQ1 outputs a fixed 5 V and 3.3 V (depending on the version).| Part No. | LP2951-33-Q1 |

DESCRIPTION
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. The 8-pin LP2951-xx-Q1 also offers additional functionality that makes it particularly suitable for battery-powered applications.
