Description
The LP2950 and LP2951 are micropower voltage regulators that are specifically designed to maintain proper regulation with an extremely low inputandminus;toandminus;output voltage differential. These devices feature a very low quiescent bias current of 75 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 powerandminus;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 aShutdown input that allows a logic level signal to turnandminus;off or turnandminus;on the regulator output.
Due to the low inputandminus;toandminus;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 dualandminus;inandminus;line, SOICandminus;8 and Micro8 surface mount packages. The andlsquo;Aandrsquo; suffix devices feature an initial output voltage tolerance andplusmn;0.5%.
