ZXTR2008Z

100V INPUT, 8.2V 30mA REGULATOR TRANSISTOR

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:

 Startup Switch in DC-DC Converters

 Networking

 Telecommunications

 Power over Ethernet (PoE)
