Ultra low drop voltage regulators compatible
with low ESR inhibit output capacitors
SOT23-5L
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.
