100 mA, Low Power Low
Dropout Voltage Regulator
The LP2950 and LP2951 are micropower voltage regulators that are
specifically designed to maintain proper regulation with an extremely
low input ? to ? output voltage differential. These devices feature a very
low quiescent bias current of 75 m A and are capable of supplying
output currents in excess of 100 mA. Internal current and thermal
limiting protection is provided.
The LP2951 has three additional features. The first is the Error
Output that can be used to signal external circuitry of an out of

regulation condition, or as a microprocessor power ? on reset. The
second feature allows the output voltage to be preset to 5.0 V, 3.3 V or
3.0 V output (depending on the version) or programmed from 1.25 V
to 29 V. It consists of a pinned out resistor divider along with direct
access to the Error Amplifier feedback input. The third feature is a
Shutdown input that allows a logic level signal to turn ? off or turn ? on
