Description

The ZXTR2005ZQ monolithically integrates a transistor, Zener diode and resistor to function as a high voltage linear regulator. The device regulates with a 5V nominal output at 15mA. It is designed for use in high voltage applications where standard linear regulators cannot be used. This function is fully integrated into a SOT89 package, minimizing PCB area and reducing number of components when compared with a multi-chip discrete solution.

Feature(s)

  • Series Linear Regulator Using Emitter-Follower Stage
  • Input Voltage = 10 to 100V (For Regulated Output Voltage)
  • Output Voltage = 5V ± 10%
  • 150kΩ Resistor to Limit Quiescent Current
  • Fully Integrated Into a SOT89 Package

Application(s)

Supply Voltage Regulation in:

  • Startup Switch in DC-DC Converters
  • Networking
  • Telecommunications
  • Power-over-Ethernet (PoE)
