LP2950, LP2951, NCV2951

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

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

the regulator output.

Due to the low input−to−output voltage differential and bias current

specifications, these devices are ideally suited for battery powered

computer, consumer, and industrial equipment where an extension of

useful battery life is desirable. The LP2950 is available in the three

pin case 29 and DPAK packages, and the LP2951 is available in the

eight pin dual−in−line, SOIC−8 and Micro8 surface mount packages.

The ‘A’ suffix devices feature an initial output voltage tolerance



0.5%.
