Description

The LD2982AM18R is a 50mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems. In sleep mode quiescent current is less than 1µA when INHIBIT pin is pulled low. Shutdown Logic Control Function is available on pin 3 (TTL compatible). This means that when the LD2982AM18R is used as local regulator, it is possible to put a part of the board in standby,decreasing the total power consumption.

An external capacitor C_BYP=10nF connected between bypass pin and GND reduce the noise to 30µVrms.

Typical application are in cellular phone, palmtop/laptop computer, personal digital assistant (PDA),personal stereo, camcorder and camera.
