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

 Startup Switch in DC-DC Converters

 Networking

 Telecommunications

 Power over Ethernet (PoE)

Features

Notes

VIN

Input Supply

Input voltage can vary from -0.3V to 100V with respect to GND; for VOUT regulated then 15V ≤ VIN ≤ 100V.

It is recommended to connect a 1µF capacitor to GND.

GND

Power Ground

This pin should be tied to the system ground.

VOUT

Voltage Output

Outputs a regulated 12V when 15V ≤ VIN ≤ 100V. When VIN < 15V, then VOUT maximum = VIN – 1.5V.

The pin can be pulled high to a maximum of +18V with respect to GND, or +12V with respect to VIN,

whichever is lower. It is recommended to connect a 10µF capacitor to GND and a minimum of 10µA to be

drawn from VOUT to maintain regulation.
