ZXTR2012FF

100V INPUT, 12V 30mA REGULATOR TRANSISTOR IN SOT23F

Description

The ZXTR2012FF 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 an SOT23F package,

minimizing PCB area and reducing number of components when

compared with a multi-chip discrete solution.

Notes

VIN

Input Supply

To maintain output regulation the input voltage can vary from 15V to 100V with respect to the GND pin. 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. It is recommended to connect a 10µF capacitor to GND. Minimum of 10µA must

be drawn from VOUT to maintain regulation. The pin can be pulled high to a maximum of 18V with respect to

ground.
