systems. The quiescent current in sleep mode is

less than 1 µA when the INHIBIT pin is pulled low.

A shutdown logic control function is available on

pin n° 3 (TTL compatible). This means that when

the device is used as local regulator, it is possible

to put a part of the board in standby, decreasing

the total power consumption. The LD2980 is

designed to work with low ESR ceramic

capacitors. Typical applications are cellular

phone, laptop computer, personal digital assistant

(PDA), personal stereo, camcorder and camera.
