LP2950/LP2951 low dropout voltage regulator, with very low quiescent current and low dropout, is ideal for battery-powered systems.
The document describes the LP2950 and LP2951 series of micropower voltage regulators designed for battery-powered systems such as portable consumer equipment and cordless telephones. Key features include extremely low quiescent current, very low dropout voltage, and positive transient protection up to 60V.
The LP2950 is available in a 3-pin TO-92 package with fixed output voltages of 3V, 3.3V, or 5V. The LP2951 offers additional features including an error flag for voltage dropout warning and a logic-controlled electronic shutdown input. It is available in 8-pin SOIC and DIP packages and supports programmable outputs from 1.24V to 29V.
