Description	Ultra low-drop voltage regulators
Datasheet	LD2981_STMicroelectronics.pdf

The LD2981 is a 100 mA 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 1 μA when INHIBIT pin is pulled low.

Ultra low dropout voltage (0.17 V typ. at 100 mA load, 7 mV typ. at 1 mA load).
Very low quiescent current (80 μA typ. at no load in on mode; max 1 μA in off mode).
Guaranteed output current up to 100 mA.
Logic-controlled electronic shutdown.
Output voltage of 2.5; 3.0; 3.3; 5.0 V.
Internal current and thermal limit.
± 0.75% tolerance output voltage available (A version).
Output low noise voltage 160 μVRMS.
Temperature range: -40 to 125 °C.
Smal.
