ZXTR2112FQ 60V INPUT, 12V 15mA REGULATOR TRANSISTOR Description Features The ZXTR2112FQ monolithically integrates a transistor, zener diode and resistor to function as a 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 SOT23 package, minimizing PCB area and reducing number of components when compared with a multi-chip discrete solution. Series Linear Regulator Using Emitter-Follower Stage Input Voltage - 15 to 60V (For Regulated Output Voltage) Output Voltage - 12V 10% Fully Integrated into a SOT23 Package Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. "Green" Device (Note 3) Qualified to AEC-Q101 Standards for High Reliability PPAP Capable (Note 4) This linear regulator is designed to meet the stringent requirements of automotive applications.

Pin Functions Pin Name Pin Function VIN Input Supply GND Power Ground VOUT Voltage Output ZXTR2112FQ Document number: DS38293 Rev. 1 - 2 Notes Input voltage can vary from -0.3V to 60V with respect to GND; for VOUT regulated then 15V VIN 60V. It is recommended to connect a 1F capacitor to GND. This pin should be tied to the system ground. Outputs a regulated 12V when 15V VIN 60V. When VIN < 15V, then VOUT maximum = VIN - 1V. The pin can be pulled high to a maximum of +17V with respect to GND, or +5V 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. 4 of 7 www.diodes.com November 2015 (c) Diodes Incorporated ZXTR2112FQ Typical Electrical Characteristics (@TA = +25C, unless otherwise specified.) 50 40 VIN =15 to 40V IOUT= 15mA Slew Rate=5V/uS COUT = 100nF VIN 30 20 10 0 0.0 10.0 100 IOUT = 0 to 30mA Slew Rate=1A/uS COUT = 100nF VIN =24V VOUT Output Voltage (V) VIN Input Voltage (V) VOUT 60 13.0 12.8 12.6 12.4 12.2 12.0 11.8 11.6 11.4 11.2 11.0 12.4 12.2 12.0 11.8 11.6 11.4 11.2 11.0 10.8 10.6 70 20.0 VOUT IOUT 0.0 0 160.0 Time(s) VOUT Output Voltage (mV) VOUT Output Voltage (mV) 120.0 1600 T J = 150C VIN = 24V 1200 T J = 100C T J = 100C 800 T J = 150C T J = 25C IOUT = 15mA 400 T J = 85C T J = 85C 0 -400 T J = -40C T J = 25C T J = -40C -800 -1200 20 30 40 50 .1 60 10 20 30 40 50 IOUT Output Current (mA) VIN Input Voltage (V) Load Regulation (Note 17) 1600 4000 VIN = 24V IQ Quiescent Current (A) VOUT Output Voltage (mV) 80.0 Load transient response Line Regulation (Note 16) IOUT = 15mA 800 400 0 -400 -800 -40 -25 0 25 50 75 100 125 150 T J = 150C 3000 IOUT = 10A T J = 100C 2000 T J = 85C T J = 25C 1000 T J = -40C 0 20 Junction temperature (C) Temperature Coefficient (Note 18) Notes: 20 40.0 Time(s) 1200 60 40 Line transient response 1800 1600 1400 1200 1000 800 600 400 200 0 -200 -400 -600 -800 80 IOUT Output Current (mA) 80 30 40 50 60 VIN Input Voltage (V) Quiescent Current 16.
