High-Voltage Linear Regulator Transistors

High-Voltage Linear Regulator Transistors

Diodes' ZXTR2000 family consists of high-voltage linear regulator transistors that boost power-circuit densities through reductions in component count and footprint. With the ability to take <100 V input and generate a fixed output voltages of 5 V, 8 V, and 12 V ±10%, the regulator transistors provide a high-voltage regulation solution where standard linear regulators cannot be used. These regulator transistors suit 48 VDC power system design in telecoms, networking, data storage, and PoE, particularly for supplying a regulated voltage into the primary-side, fan, or micro controllers.

Features
  • Smaller footprint - monolithically integrating a transistor, Zener, and resistor into a single package helps to reduce components count and footprint
  • 100 VIN - high-voltage capability means that the input will effectively tolerate spurious voltages up to a maximum of 100 V, ensuring a good safety margin in the event of transient over-voltage conditions
  • Line and load regulation - output voltage is regulated under both line and load fluctuations ensuring the continued supply and preventing latch-up due to transient voltage drops
Applications
  • Telecoms
  • Networking and data storage
  • Power over Ethernet (PoE)
