DESCRIPTION

The LD2980 series are 50mA fixed-output voltage

regulator. The low drop-voltage and the ultra low

SCHEMATIC DIAGRAM

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 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 capacitor. Typical

applications are in cellular phone, palmtop/laptop

computer, personal digital assistant (PDA),

personal stereo, camcorder and camera.
