A Product Line of Diodes Incorporated ZXTR2108F 60V INPUT, 8V 15mA REGULATOR TRANSISTOR Description Features The ZXTR2108F monolithically integrates a transistor, zener diode and resistor to function as a linear regulator. The device regulates with an 8V 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 the number of components when compared with a multi-chip discrete solution. Applications Mechanical Data Supply voltage regulation for: 24V to 8V Rails Other Customized Input Rails Series Linear Regulator Using Emitter-Follower Stage Input Voltage = 10 to 60V (For regulated output voltage) Output Voltage = 8V ± 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 Case: SOT23 Case Material: Molded Plastic. “Green” Molding Compound.

Pin Function Pin Name Pin Function VIN Input Supply GND Power Ground VOUT Voltage Output ZXTR2108F Document number: DS37330 Rev. 1 - 2 Notes Input voltage can vary from -0.3V to 60V with respect to GND; for VOUT regulated then 10V ≤ VIN ≤ 60V. It is recommended to connect a 1µF capacitor to GND. This pin should be tied to the system ground. Outputs a regulated 8V when 10V ≤ VIN ≤ 60V. When VIN < 10V, then VOUT maximum = VIN – 1V. The pin can be pulled high to a maximum of +13V 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. 4 of 7 www.diodes.com May 2015 © Diodes Incorporated A Product Line of Diodes Incorporated ZXTR2108F (@TA = +25°C, unless otherwise specified.) 8.4 VIN Input Voltage (V) 70 8.2 8.0 VOUT 60 50 7.8 40 7.6 7.4 VIN =10 to 40V VIN 30 IOUT= 15mA Slew Rate=5V/uS COUT = 100nF 20 10 0 0.0 7.2 7.0 6.8 6.6 20.0µ 10.0µ 9.0 100 8.8 8.6 IOUT = 0 to 30mA 8.4 VIN =24V Slew Rate=1A/uS COUT = 100nF VOUT 8.2 40 7.6 IOUT 7.4 7.2 7.0 0.0 20 40.0µ Time(s) 80.0µ 120.0µ Time(s) 1200 1000 1000 800 800 600 400 T J = 100°C 200 T J = 150°C 0 T J = 85°C T J = 25°C -200 -400 20 30 40 VIN = 24V T J = 100°C 600 T J = 85°C 400 200 0 T J = 25°C -400 -600 IOUT = 15mA -800 10 T J = 150°C -200 T J = -40°C -600 50 60 -800 0.1 T J = -40°C 10 20 30 Line Regulation (Note 15) 600 IOUT = 15mA 4000 IQ Quiescent Current (A) VIN = 12V 50 Load Regulation (Note 16) 1000 800 40 IOUT Output Current (mA) VIN Input Voltage (V) VOUT Output Voltage (mV) 0 160.0µ Load transient response VOUT Output Voltage (mV) VOUT Output Voltage (mV) 60 8.0 7.8 Line transient response T J = 150°C IOUT = 10µA T J = 100°C 3000 400 T J = 85°C 2000 200 0 T J = 25°C 1000 -200 -400 -40 -25 Notes: 80 IOUT Output Current (mA) 80 VOUT Output Voltage (V) Typical Electrical Characteristics 0 25 50 75 100 125 150 T J = -40°C 0 10 20 30 40 50 Junction temperature (°C) VIN Input Voltage (V) Temperature Coefficient (Note 17) Quiescent Current 60 15.
