TDA3665 Product details

Description

The TDA3665 is a fixed 8.5 V voltage regulator with a very low dropout voltage and quiescent current, which operates over a wide supply voltage range. TDA3665: VP ≤ 45 V, 40 °C ≤ Tamb ≤ +125 °C and SO4 package (automotive) TDA3665AT: VP ≤ 45 V, 40 °C ≤ Tamb ≤ +125 °C and SO8 package (automotive).

Features

Fixed 8.5 V, 100 mA regulator.
Supply voltage range up to 33 V (45 V).
Very low quiescent current of 15 µA (typical value).
