Description
The ZXTR2005K 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 TO252 package, minimizing PCB area and reducing number of components when compared with a multi-chip discrete solution.

Features
• 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 TO252 Package
