HT7123-2 - 30mA TinyPower LDO

Download the HT7123-2 datasheet PDF. This datasheet also covers the HT7121-2 variant, as both devices belong to the same 30ma tinypower ldo family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT71xx-2 series is a set of three-terminal low power high voltage regulators implemented in CMOS technology.

They allow input voltages as high as 30V.

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

Key Features

  • Low power consumption.
  • Low voltage drop.
  • Low temperature coefficient.
  • High input voltage (up to 30V).
  • Output voltage accuracy: tolerance ±1%.
  • Package types: 3-pin TO92, 3-pin SOT89 and 5-pin SOT23.
