ZXTR2012K

100V INPUT, 12V 50mA REGULATOR TRANSISTOR

Description

The ZXTR2012K 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

’s 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 a number of components when

compared with a multi-chip discrete solution.

Applications

Supply voltage regulation in:

 Startup switch in DC-DC converters

 Networking

 Telecom

 Power over Ethernet (PoE)
