ZXTR2005K
100V INPUT, 5V 50mA REGULATOR TRANSISTOR
Description
The ZXTR2005K monolithically integrates a transistor, Zener diode
and resistor to function as a high voltage linear regulator. The device
regulates with a 5V 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 TO252 package,
minimizing PCB area and reducing number of components when
compared with a multi-chip discrete solution.

Notes
Input voltage can vary from -0.3V to 100V with respect to GND; for VOUT regulated then 10V ≤ VIN ≤ 100V.
It is recommended to connect a 1µF capacitor to GND.
This pin should be tied to the system ground.
Outputs a regulated 5V when 10V ≤ VIN ≤ 100V. When VIN < 10V, then VOUT maximum = VIN – 1.5V.
The pin can be pulled high to a maximum of +11V with respect to GND, or +5V 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.
