INTERNAL CURRENT AND THERMAL LIMIT

± 0.75% TOLERANCE OUTPUT VOLTAGE

AVAILABLE (A VERSION)

SOT23-5L

SOT-89

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 assistant (PDA),

personal stereo, camcorder and camera.

OUTPUT LOW NOISE VOLTAGE 160µVRMS

TEMPERATURE RANGE: -40 TO 125°C
