1 / 13 page TS431 Adjustable Precision Shunt Regulator 1/13 Version: F07 TO-92 SOT-89 SOT-23 SOP-8 General Description TS431 series integrated circuits are three-terminal programmable shunt regulator diodes. These monolithic IC voltage references operate as a low temperature coefficient zener which is programmable from VREF to 36 volts with two external resistors. These devices exhibit a wide operating current range of 1.0 to 100mA with a typical dynamic impedance of 0.22Ω. The characteristics of these references make them excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5V reference makes it convenient to obtain a stable reference from 5.0V logic supplies, and since The TS431 series operates as a shunt regulator, it can be used as either a positive or negative stage reference. Features ● Precision Reference Voltage TS431 – 2.495V ±2% TS431A – 2.495V ±1% TS431B – 2.495V ±0.5% ● Equivalent Full Range Temp. Coefficient: 50ppm/ ºC ● Programmable Output Voltage up to 36V ● Fast Turn-On Response ● Sink Current Capability of 1~100mA ● Low Dynamic Output Impedance: 0.2Ω ● Low Output Noise Block Diagram Ordering Information Part No. Package Packing TS431xCT B0 TO-92 1Kpcs / Bulk TS431xCT B0G TO-92 1Kpcs / Bulk TS431xCT A3 TO-92 2Kpcs / Ammo TS431xCT A3G TO-92 2Kpcs / Ammo TS431xCX RF SOT-23 3Kpcs / 7” Reel TS431xCX RFG SOT-23 3Kpcs / 7” Reel TS431xCY RM SOT-89 1Kpcs / 7” Reel TS431xCY RMG SOT-89 1Kpcs / 7” Reel TS431xCS RL SOP-8 2.5Kpcs / 13” Reel TS431xCS RLG SOP-8 2.5Kpcs / 13” Reel Note: Where xx denotes voltage tolerance Blank: ±2%, A: ±1%, B: ±0.5% “G” denotes for Halogen free products Absolute Maximum Rating (Ta = 25oC unless otherwise noted) Parameter Symbol Limit Unit Cathode Voltage (Note 1) VKA 37 V Continuous Cathode Current Range IK -100 ~ +150 mA Reference Input Current Range IREF -0.05 ~ +10 mA TO-92 0.625 SOT-23 0.30 Power Dissipation SOT-89 / SOP-8 PD 0.50 W Junction Temperature TJ +150 oC Operating Temperature Range TOPER 0 ~ +70 oC Storage Temperature Range TSTG -65 ~ +150 oC Note 1: Voltage values are with respect to the anode terminal unless otherwise noted.
