HT7550-7 - 100mA TinyPower LDO

Download the HT7550-7 datasheet PDF. This datasheet also covers the HT7521-7 variant, as both devices belong to the same 100ma tinypower ldo family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT75xx-7 is a low power high voltage series of regulators implemented in CMOS technology which has the advantages of low voltage drop and low quiescent current.

They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 2.1V to 12.0V.

Key Features

  • Low power consumption.
  • Low voltage drop.
  • Low temperature coefficient.
  • High input voltage.
  • up to 30V.
  • Output voltage accuracy: tolerance ±2%.
  • Over current protection.
  • Over temperature protection.
  • Chip enable/disable function.
  • 3-pin SOT89 and 5-pin SOT23 packages.
