ZXTR2105F
60V INPUT, 5V 15mA REGULATOR TRANSISTOR
Description
Features
The ZXTR2105F monolithically integrates a transistor, zener diode
and resistor to function as a linear regulator. The device regulates
with a 5V nominal output at 15mA. It is designed for use in highvoltage applications where standard linear regulators cannot be used.
This function is fully integrated into a SOT23 package, minimizing
PCB area and reducing the number of components when compared
with a multi-chip discrete solution.

Notes
Input voltage can vary from -0.3V to 60V with respect to GND; for VOUT regulated then 7V ≤ VIN ≤ 60V. It is
recommended to connect a 1µF capacitor to GND.
This pin should be tied to the system ground.
Outputs a regulated 5V when 7V ≤ VIN ≤ 60V. When VIN < 7V, then VOUT maximum = VIN – 1V.
The pin can be pulled high to a maximum of +10V with respect to GND, or +5V with respect to V IN,
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.
