HT73H40 - 40V 250mA LDO

Download the HT73H40 datasheet PDF. This datasheet also covers the HT73H21 variant, as both devices belong to the same 40v 250ma ldo family and are provided as variant models within a single manufacturer datasheet.

Description

The HT73Hxx series is a set of low power consumption high voltage regulator implemented in a BCD technology, which ensures low voltage drop and low quiescent current.

They allow input voltages as high as 40V.

They are available with several fixed output voltages ranging from 2.1V to 5.0V.

Features

  • Low power consumption.
  • Low voltage drop.
  • Low temperature coefficient.
  • High input voltage (up to 40V).
  • Output voltage accuracy: tolerance ±1.5%.
  • Soft start function.
  • Over current protection.
  • Over temperature protection.
  • Package types: 3-pin SOT89, 5-pin SOT23.
