SLVSAW6E – JUNE 2011 – REVISED NOVEMBER 2014 LP2951-xx-Q1 Adjustable Micropower Voltage Regulators With Shutdown
1 Features 3 Description The LP2951-xx-Q1 devices are bipolar, low-dropout
voltage regulators that can accommodate a wide
input supply-voltage range of up to 35 V. The 8-pin
LP2951-xx-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-xxQ1 outputs a fixed 5 V and 3.3 V (depending on the
version). 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 1.235 V to 30 V. 1 Qualified for Automotive Applications
