Additional features available with the LP2951 also
include an error flag output that warns of a low output
voltage, which is often due to failing batteries on the
input. This may also be used as a power-on reset. A
logic-compatible shutdown input is also available which
enables the regulator to be switched on and off. This
part may also be pin-strapped for a 5V output, or
programmed from 1.24V to 29V with the use of two
external resistors.
The LP2950 is available as either a -02 or -03 version.
The -02 and -03 versions are guaranteed for junction

temperatures from –40°C to +125°C; the -02 version has
a tighter output and reference voltage specification
range over temperature. The LP2951 is available as an
-02 or -03 version.
The LP2950 and LP2951 have a tight initial tolerance
(0.5% typical), a very low output voltage temperature
coefficient which allows use as a low-power voltage
reference, and extremely good load and line regulation
(0.05% typical). This greatly reduces the error in the
overall circuit, and is the result of careful design
techniques and process control.
