The LP2951-50DRGR is a single channel, fixed output micropower low dropout (LDO) voltage regulator 8 pin WSON package. This bipolar low dropout voltage regulator can be used as a regulator or reference. It provides adjustable output by leaving the SENSE and VTAP pins open and connecting FEEDBACK to an external resistor divider. The LP2951-50 has shutdown capability and remote sense capability for optimal output regulation and accuracy. It also offers additional functionality that makes it particularly suitable for battery powered applications. This regulator is designed to minimize all error contributions to the output voltage. The device can be used as either low power voltage references or 100mA regulator with a tight output tolerance (0.5% at 25°C), a very low output voltage temperature coefficient (20ppm typical), extremely good line and load regulation.
