ZXTR2012K 100V INPUT, 12V 50mA REGULATOR TRANSISTOR Description Features 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 Mechanical Data Supply voltage regulation in: Startup switch in DC-DC converters Networking Telecom Power over Ethernet (PoE) Series Linear Regulator Using Emitter-Follower Stage Input Voltage = 15V to 100V (For regulated output voltage) Output Voltage = 12V 10% 150k resistor to limit quiescent current Fully integrated into a TO252 package Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.

It is recommended to connect a 1F capacitor to GND. VIN Input Supply 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 10F capacitor to GND and a minimum of 10A to be drawn from VOUT to maintain regulation.
