Description

General part information

LDQ40 Series

The LDQ40 is a high accuracy voltage regulator, which provides 250 mA of current.

It is available in an SOT23 5L, DFN 2x2 6L package, to maximize space saving.

The device is stabilized with a small ceramic capacitor on the output. The low drop, low quiescent current, and short-circuit protection make the LDQ40 suitable for low-power battery-operated applications.
