Description

General part information

LP2951-Q1 Series

The LP2951-Q1 is a wide input low-dropout regulator (LDO) supporting an input voltage range from 2V to 30V and can supply up to 100mA of load current. The 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 VTAP pins together, the LP2951-Q1 gives 3.3V or 5V fixed output voltages. Alternatively, leave the SENSE and VTAP pins open and connect FEEDBACK to an external resistor divider. This configuration allows the output to be set to any value between 1.2V to 29V.

The LP2951-Q1 has a ERROR output that monitors the voltage at the feedback pin to indicate the status of the output voltage. The SHUTDOWN input and ERROR output are used for sequencing multiple power supplies in the system.
