LD2982 - VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR WITH INHIBIT FUNCTION / LOW ESR CAP. COMPATIBLE

Description

The LD2982 is a 50mA fixed output voltage regulator.

The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems.

pin is pulled low.
