Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.

Description

The LD2980ABM30TR series are 50mA fixed-output voltage regulator. The low drop-voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery powered systems.

The quiescent current in sleep mode is less than 1µA when INHIBIT pin is pulled low. Shutdown Logic Control function is available on pin n.3 (TTL compatible). This means that when the LD2980ABM30TR is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. The LD2980ABM30TR is designed to work with low ESR ceramic capacitor. Typical applications are in cellular phone, palmtop/laptop computer, personal digital assistant (PDA),personal stereo, camcorder and camera.
