1 / 10 page TS431-Z Adjustable Precision Shunt Regulator 1/10 Version: B11 SOT-23 General Description TS431 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 to 250mA with a typical dynamic impedance of 0.2 Ω. 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 2.495V reference makes it convenient to obtain a stable reference from 5.0V logic supplies, and since The TS431 operates as a shunt regulator, it can be used as either a positive or negative stage reference . Features ● Programmable Output Voltage up to 36V ● Fast Turn-On Response ● Sink Current Capability: 200mA ● Low Dynamic Output Impedance: 0.2 (Typ) ● Min. Operating Cathode Current: 0.2mA (Typ) ● Halogen Free Ordering Information Part No. Package Packing TS431ACX-Z RFG SOT-23 3Kpcs / 7” Reel TS431BCX-Z RFG SOT-23 3Kpcs / 7” Reel Note: TS431A – VREF 2.495V ±1% TS431B – VREF 2.495V ±0.5% “G” denotes for Halogen free products Block Diagram Absolute Maximum Rating (Ta = 25 oC unless otherwise noted) Parameter Symbol Limit Unit Cathode Voltage VKA 36 V Continuous Cathode Current Range IK +250 mA Reference Input Current Range IREF 10 mA Power Dissipation PD 0.25 W Operating Temperature Range TOPER -20 ~ +85 oC Junction Temperature TJ -40 ~ +125 oC Storage Temperature Range TSTG -40 ~ +125 oC Thermal Resistance Junction to Ambient Ө JA 156 oC/W Note: ӨJA is measured with the PCB copper area of approximately 1 in 2 (Multi-Layer) Pin Definition: 1.
