Low-Dropout Voltage Regulator, LP2951-50DR, Texas Instruments
The LP2951-50DR 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 LP2951-50DR 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 LP2951-50DR gives a 3.3V or 5V fixed output voltage. 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 an 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 a power supply in the system.
