TDA3668AT - Very low dropout voltage/quiescent current 5V regulator

Description

The TDA3668AT is a fixed 5 V voltage regulator with a very low dropout voltage and quiescent current, which operates over a wide supply voltage range.

The regulator should use a supply voltage of VP ≤ 50 V.

40 °C ≤ Tamb ≤ +125 °C, and it is available as an auto

Features

  • Fixed 5 V, 100 mA regulator.
  • Supply voltage range up to 50 V.
