TL431ACLP
by TI(德州仪器)
An adjustable reference for feedback and regulation circuits, TI's TL431ACLP is a three-terminal shunt regulator. The TL431 family is commonly used to establish a reference level in power-supply control loops, with external circuitry setting the operating point. This version uses a through-hole TO-92 package. Its free KiCad files contain a three-pin symbol, the three-pad footprint TO-92-3_L4.9-W3.7-P1.27-L, and an included 3D model for assembly visualization. Practical verification is backed by 1 ProtoFlow engineer having used the conversion in real designs. The TL431ACLP can be opened directly in ProtoFlow to review its connections and through-hole layout.
