DESCRIPTION
The LD2981 series are 100 mA fixed-output
voltage regulator. The ultra drop-voltage and the
ultralow quiescentcurrent makethem particularly
suitablefor low noise, low power applications and
in battery poweredsystems.
In sleep mode quiescent current is less than 1
μ
A
when INHIBIT pis 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. Typlical application are in
cellular
phone,
palmtop/laptop
personal digital assistant (PDA), personal stereo,
camcorderand camera.
