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.
