TPR431B-S3TR

TPR431, TPR432 Precision Programmable Reference Features Description  Reference Voltage Tolerance at 25°C The TPR431 and TPR432 are adjustable shunt voltage references with guaranteed temperature stability over the operating temperature range. The device temperature range is extended from −40 °C up to +125 °C. The output voltage can be set to any value between 2.5 and 36 V with two external resistors. The TPR431 operates with a wide current range from 1 to 80 mA with a typical dynamic impedance of 0.2 Ω. − 0.5% (B Grade) − 1% (A Grade)  Operation from –40°C to 125°C  0.2-Ω Typical Output Impedance  Sink Current Capability: 1 mA to 80 mA  Adjustable Output Voltage: VREF to 36V Applications  Power  Led Lighting  Current Sensing  Instrumentation  Industry Pin Configuration CATHODE 1 REF 2 TPR431 TPR432 3-Pin SOT23 3-Pin SOT23 3 REF 1 CATHODE 2 3 ANODE ANODE Functional Block Diagram CATHODE REF VREF ANODE www.3peakic.com.cn 1 / 10 Rev.A.1 TPR431, TPR432 Precision Programmable Reference Product Family Table Order Number Grade Voltage Tolerance Package TPR431B-S3TR B 0.5% SOT23G-3 TPR431A-S3TR A 1% SOT23G-3 TPR432B-S3TR B 0.5% SOT23G-3 TPR432A-S3TR A 1% SOT23G-3 www.3peakic.com.cn 2 / 10 Rev.A.1 TPR431, TPR432 Precision Programmable Reference Table of Contents Features .............................................................................................................................................................. 1 Applications ....................................................................................................................................................... 1 Description ......................................................................................................................................................... 1 Pin Configuration ............................................................................................................................................... 1 Functional Block Diagram ................................................................................................................................ 1 Product Family Table ......................................................................................................................................... 2 Revision History ................................................................................................................................................ 4 Specifications .................................................................................................................................................... 5 Absolute Maximum Ratings .......................................................................................................................... 5 ESD, Electrostatic Discharge Protection ...................................................................................................... 5 Recommended Operating Conditions .......................................................................................................... 5 Thermal Information ..................................................................................................................................... 5 Electrical Characteristics .............................................................................................................................. 6 Typical Performance Characteristics ............................................................................................................ 7 Tape and Reel Information ................................................................................................................................ 8 Package Outline Dimensions ........................................................................................................................... 9 SOT23G-3 .................................................................................................................................................... 9 Order Information ............................................................................................................................................ 10 www.3peakic.com.cn 3 / 10 Rev.A.1 TPR431, TPR432 Precision Programmable Reference Revision History Data Revision 2021-06-12 Rev A.0 2021-11-01 Rev.A.1 www.3peakic.com.cn Notes Initial Version. 1.
