Description

The ZXTR2008Z monolithically integrates a transistor, Zener diode

and resistor to function as a high voltage linear regulator. The device

regulates with an 8.2V 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.

Applications

Supply voltage regulation in:

 Networking

 Telecom

 Power Over Ethernet (PoE)

To maintain output regulation the input voltage can vary from 12V to 100V with respect to the GND pin. It is recommended to connect a 1µF capacitor to GND.

Outputs a regulated 8.2V. It is recommended to connect a 10µF capacitor to GND. Minimum of 10µA must be drawn from V

to maintain regulation. The pin can be pulled high to a maximum of 14.5V with respect
