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

Networking
Telecom
Power Over Ethernet (PoE)
