Rated for an output current of 15 mA and a cathode current as low as 100 µA, it suits always-on bias or reference circuits where quiescent power must be minimised. ## Package and mounting — SOT-89-3 Housed in a TO-243AA (SOT-89-3) surface-mount package, the TLV431AQPK is a three-terminal device with a large collector pad for heat sinking. The supplier device package is SOT-89-3.","metaTitle":"TLV431AQPK Adjustable Shunt Regulator, 1.24V-6V, ±1%","metaDescription":"TLV431AQPK adjustable shunt reference from TI.

The TLV431AQPK also offers a tighter ±1% tolerance."},{"question":"Can TLV431AQPK be used as a comparator?","answer":"Yes, like other shunt regulators in the TL431 family, the TLV431AQPK can function as a voltage comparator when the reference pin is driven above or below the internal 1.24V threshold — the output (cathode) switches between high-impedance and active-low states."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV431AQPK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV431AQPK when reusing this data.
