DESCRIPTION
The LD2981 series are 100mA 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 device is
used as local regulator, it is possible to put a part
of the board in standby, decreasing the total
power consumption. The LD2981 is designed to
work with low ESR ceramic capacitor. Typical
applications are in cellular phone, palmtop/laptop
computer,
personal
digital
personal stereo, camcorder and camera.
