ZXTR2012Z

100V INPUT, 12V 30mA REGULATOR TRANSISTOR

Description

The ZXTR2012Z monolithically integrates a transistor, Zener diode

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

regulates with a 12V 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)
