The LP2951 is a wide input low-dropout regulator (LDO) supporting an input voltage range from 2V to 30V and up to 100mA of load current. 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 LP2950/LP2951 can give 5V or 3.3V fixed output voltages. 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 1.2V to 29V.
The LP2951 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 can be used for sequencing multiple power supplies in the system.
The LP2951 is available in a 3-pin 4.83mm x 4.83mm TO-92(LP), an 8-pin 4.9mm x 6.0mm SOIC(D), and 8-pin 3mm x 3mm SON(DRG) package.
