LDQ40 - 250mA low-dropout LDO

General Description

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.

Key Features

  • AEC-Q100 grade 1 qualified.
  • Operating temperature range: -40 °C < TJ < 150 °C.
  • Input voltage from 3.3 V to 40 V.
  • Dropout voltage (500 mV typ. at 250 mA load).
  • Low ground current (2 μA typ. at no load).
