The LP2951 Series 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 µA and are capable of supplying output currents in excess of 100 mA. Internal current and thermal limiting protection is provided.

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%.
