3 Description
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.
