TL431ACLPR
Texas InstrumentsTL431ACLPR is a Texas Instruments adjustable precision shunt regulator in TO-92 — for feedback references in flyback and buck supplies: the industry-standard programmable zener. 2.5 V reference at ±1% (A-grade), programmable output to 36 V, 1–100 mA cathode current, 0.2 Ω typical dynamic impedance. Heat evidence: TI analog demand remains firm with select tightness — the TL431 is the highest-volume voltage reference in the industry and a permanent distributor staple. Selection advice: the ACLPR code is A-grade (1%) commercial-temp in TO-92 on reel — for SMT designs order the TL431ACPK (SOT-89) or TL431ACDBZR (SOT-23) instead of bending TO-92 leads. Parameters verified against Texas Instruments documentation.
