Overview

The HT75Rxx-1 series are three-terminal, low-power, high-voltage regulators capable of delivering 150mA output current, with input voltages up to 30V, and multiple fixed output voltage options ranging from 2.1V to 12.0V. This series incorporates a soft-start function to control the output slew rate and prevent overshoot during power-up. Although primarily designed as fixed voltage regulators, they can be combined with external components to achieve variable voltage and current outputs.

Applications

  • Battery-powered devices
  • Communication equipment
  • Audio/video devices

Key features

  • Low power consumption
  • Low dropout voltage
  • Low temperature coefficient
  • Maximum input voltage: 30V
  • Output voltage accuracy: ±1%
  • Low quiescent current: 1μA (typical)
  • High output current: 150mA
  • Soft-start function
  • Compatible with 1μF ceramic output capacitor
  • Package types: 3-pin SOT89, 5-pin SOT23
