The LP2951-Q1 is a bipolar, low-dropout voltage regulator that can accommodate a wide input supply-voltage range of up to 35 V. The 8-pin LP2951-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 V TAP pins together, the LP2951-Q1 outputs a fixed 5 V and 3.3 V (depending on the version). Alternatively, by leaving the SENSE and V TAP 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 LP2951-Q1 device is designed to minimize all error contributions to the output voltage. With a tight output tolerance (0.5% at 25°C), a very low output voltage temperature coefficient (20 ppm typical), extremely good line and load regulation (0.3% and 0.4% typical), and remote sensing capability, the device can be used as either a low-power voltage reference or a 100-mA regulator.
