El TL431 actúa como referencia shunt de precisión manteniendo 2.495 V en su terminal REF mediante una referencia bandgap interna y un amplificador operacional de error que comanda un transistor NPN Darlington de colector abierto. Un divisor resistivo de precisión (R1 y R2) establece la tensión de salida nominal en 5.01 V (aprox. 5.0 V). La resistencia en serie R3 (470 Ω) reduce la tensión desde los 10 V de entrada, proporcionando unos 10.4 mA de corriente de polarización de cátodo para asegurar una operación por encima del requisito mínimo de 1.0 mA (Imin). El condensador de entrada C1 (100 nF) desacopla los transitorios de la fuente. La estabilidad requiere respetar los límites de carga capacitiva (TI fig. 8-16), evitando cargas directas en el rango prohibido de 10 nF a 3 µF.","### 1. Alimentación y desacoplo de entrada\nUna tensión continua nominal de 10 V (no regulada o pre-regulada) se conecta al puerto de entrada P1. El condensador cerámico C1 (100 nF, 50 V) proporciona desacoplo de alta frecuencia directamente en la entrada para suprimir ruido y rizado del riel.\n\n### 2. Resistencia de balasto en serie\nLa resistencia R3 (470 Ω, 1%, 1\u002F4 W) se ubica entre la entrada de 10 V y el nodo de cátodo regulado a 5.0 V. Con una caída de 5.0 V en R3, la corriente total entregada es I_RS = (10 V - 5.0 V) \u002F 470 Ω ≈ 10.64 mA. Esta corriente se divide entre el divisor de realimentación (≈ 0.25 mA), el cátodo del TL431 (≈ 10.39 mA) y cualquier carga externa conectada en P2.\n\n### 3. Ajuste de tensión y realimentación\nEl amplificador de error interno compara la tensión en el pin 1 (REF) con la referencia interna compensada en temperatura de 2.495 V. La tensión de salida se programa mediante R1 y R2 según V_O = V_ref * (1 + R1\u002FR2) + I_ref * R1. Con R1 = 10 kΩ, R2 = 10 kΩ e I_ref ≈ 2 µA, la salida nominal es 2.495 V * 2 + 20 mV = 5.01 V ≈ 5.0 V.\n\n### 4. Mecanismo de regulación shunt\nSi V_OUT se eleva levemente, V_REF supera 2.495 V, haciendo que el amplificador aumente la corriente de base del transistor NPN. El transistor desvía más corriente de cátodo a GND a través del pin 2 (ANODE), incrementando la caída en la resistencia en serie R3 y restableciendo V_OUT al valor programado. Por el contrario, si V_OUT baja, el transistor conduce menos, restableciendo la regulación.\n\n### 5. Estabilidad del lazo y carga capacitiva\nEl amplificador de error interno posee una elevada ganancia en lazo abierto optimizada para regulación shunt estable. No obstante, como documenta TI SLVS543S figura 8-16, conectar cargas capacitivas directamente entre cátodo y ánodo en el rango de 10 nF a 3 µF introduce un desplazamiento de fase polo-cero desfavorable que reduce el margen de fase y causa oscilaciones. El circuito es totalmente estable sin condensador de carga o con C_L ≥ 10 µF (con amortiguamiento por ESR electrolítica típica).",[26,29,32,35,38,41,44],{"label":27,"value":28},"Tensión de alimentación nominal","10 V nominal (opera de 8 V a 15 V con dimensionamiento adecuado de R3)",{"label":30,"value":31},"Tensión regulada de salida","≈ 5.01 V cálculo nominal (2.495 V * 2 + 2 µA * 10 kΩ)",{"label":33,"value":34},"Tensión de referencia (Vref)","2.495 V nominal; de 2.440 V a 2.550 V grado estándar (TI SLVS543S §6.5)",{"label":36,"value":37},"Corriente de cátodo (IK)","≈ 10.4 mA nominal sin carga (rango de operación seguro: 1.0 mA a 100 mA)",{"label":39,"value":40},"Corriente del divisor de realimentación","≈ 250 µA (cálculo Vref \u002F R2 = 2.495 V \u002F 10 kΩ)",{"label":42,"value":43},"Resistencia de balasto en serie (R3)","470 Ω, 1%, 0.25 W (disipación nominal ≈ 53 mW)",{"label":45,"value":46},"Impedancia dinámica (|ZKA|)","0.2 Ω típico, 0.5 Ω máximo (f \u003C 1 kHz)",[48,49,50],"Referencia de tensión precisa de 5.0 V para convertidores analógico a digital (ADC)","Tensión de referencia estable para comparadores y umbrales de sensores","Circuito de referencia formativo para regulación shunt y control bandgap",[52,57,62,66],{"title":53,"trap":54,"solution":55,"severity":56},"Inestabilidad por carga capacitiva y oscilación límite","Conectar condensadores de desacoplo directamente entre cátodo y ánodo en el rango de 10 nF a 3 µF causa oscilación parasitaria de alta frecuencia por pérdida de margen de fase (TI SLVS543S figura 8-16).","Deje la salida sin condensador (divisor puramente resistivo) o utilice un condensador CL ≥ 10 µF con ESR electrolítica normal (0.5 a 2 Ω).
