Dos reguladores fijos generan los carriles: un LM7915 para −15 V y un LM7815 para +15 V (TI lo dibuja como LM340T-15, que la hoja de datos del LM340 especifica junto con el LM7815). Por sí solos los dos carriles podrían diferir hasta 1,2 V, porque cada regulador solo garantiza un 4% (de 14,4 V a 15,6 V). El circuito elimina esa diferencia en dos pasos: un trimmer fija la salida negativa en exactamente −15,0 V, y un amplificador operacional desplaza el pin GND del regulador positivo hasta que un divisor de resistencias al 1% entre los carriles marca 0 V, lo que obliga al carril positivo a tener la misma magnitud. Los diodos de protección impiden que cualquiera de las salidas pase a la polaridad contraria. Las entradas sin regular ±VIN provienen de un rectificador y un filtro aparte (TI midió el rizado con condensadores de entrada de 3000 µF); no se dibujan.","### 1. Dos reguladores con un COMMON compartido\nU1 (LM7815) reduce +VIN a +15 V y U2 (LM7915) regula −VIN a −15 V. COMMON es el punto de 0 V entre los carriles, compartido con la carga. Cada regulador mantiene su salida a 15 V fijos de su propio pin GND, y en este circuito ninguno de los pines GND está unido directamente a COMMON: eso es lo que permite ajustar ambas salidas.\n\n### 2. Ajuste del carril negativo\nEl pin GND de U2 está sobre R1 (50 Ω) a COMMON. R3 está conectado entre las dos salidas y su cursor inyecta corriente a través de R2 (1 kΩ) en R1, subiendo o bajando el pin GND y con él la salida de −15 V. Con el cursor en cualquiera de los extremos, el desplazamiento es de aproximadamente:\n$$\\Delta V_{GND} \\approx \\pm V_W \\frac{R_1}{R_1 + R_2} = \\pm 15\\text{ V} \\cdot \\frac{50\\,\\Omega}{1050\\,\\Omega} \\approx \\pm 0.71\\text{ V}$$\nLa propia corriente del pin GND del regulador, 1,5 mA típicos, también circula por R1 y añade unos 75 mV; el ajuste también lo compensa. R3 se ajusta para tener exactamente −15,0 V en la salida.\n\n### 3. El carril positivo sigue al negativo\nR4 y R5, ambas de 10 kΩ 1%, forman un divisor entre +15 V y −15 V. El LM307 compara su punto medio (pin 2) con COMMON (pin 3) y controla el pin GND de U1 desde el pin 6. Si el carril positivo está demasiado alto, el punto medio sube por encima de 0 V, la salida del amplificador operacional baja y hace bajar U1 en la misma cantidad. El lazo se estabiliza cuando el punto medio está a 0 V:\n$$V_{+} = -V_{-} \\cdot \\frac{R_4}{R_5}$$\nCon R4 = R5 la salida positiva es igual a la magnitud de la negativa, así que ajustar R3 fija ambos carriles. TI indica que la tolerancia de R4 y R5 determina lo bien que coinciden las salidas. La salida del amplificador solo se desplaza la diferencia entre la tensión propia del LM7815, de 14,4 V a 15,6 V, y el objetivo, y debe absorber la corriente de reposo de U1, hasta 8 mA.\n\n### 4. Condensadores de salida y diodos de protección\nC1 y C2 (25 µF cada uno) están en las salidas. TI exige un condensador de salida en el LM79xx para la estabilidad: 1 µF de tántalo sólido o 25 µF electrolítico de aluminio. D1 y D2 (1N4001) están polarizados en inversa en funcionamiento normal; TI los dibuja sin describir su función. Si una salida es arrastrada más allá de COMMON hacia la polaridad contraria, por ejemplo cuando un regulador arranca antes que el otro con una carga conectada entre los carriles, el diodo conduce y limita la tensión inversa sobre ese regulador a aproximadamente una caída de diodo.\n\n### 5. Entradas, margen y calor\nC4 y C5 solo son necesarios si los condensadores de filtro de la fuente sin regular están a más de 3 pulgadas (unos 7,6 cm). El LM7815 necesita al menos 17,7 V para su especificación de regulación de línea y admite como máximo 35 V; el LM7915 está especificado de −17,5 V a −30 V en sus pruebas de regulación de línea y admite −35 V. Cada regulador disipa la tensión que cae en él multiplicada por la corriente de carga:\n$$P_D = (V_{IN} - V_{OUT}) \\cdot I_{OUT} = (20\\text{ V} - 15\\text{ V}) \\cdot 1\\text{ A} = 5\\text{ W}$$\nA ese nivel ambos reguladores necesitan disipador.",[26,29,32,35,38,41,44,47],{"label":27,"value":28},"Tensión de salida regulada","+15 V y −15 V con seguimiento; hasta 1 A (figura 8 de TI)",{"label":30,"value":31},"Regulación de carga con ΔIL = 1 A","40 mV (−15 V), 2 mV (+15 V) (tabla de la figura 8 de TI)",{"label":33,"value":34},"Rizado de salida","100 µVrms con CIN = 3000 µF, IL = 1 A (tabla de la figura 8 de TI)",{"label":36,"value":37},"Ruido de salida","150 µVrms, 10 Hz ≤ f ≤ 10 kHz (tabla de la figura 8 de TI)",{"label":39,"value":40},"Estabilidad térmica","50 mV (tabla de la figura 8 de TI)",{"label":42,"value":43},"Rango de tensión de entrada","+VIN de 17,7 V a 35 V (LM7815, TI SNOSBT0L); −VIN de −17,5 V a −35 V (LM7915, TI SNOSBQ7C)",{"label":45,"value":46},"Rango de ajuste de salida","≈ ±0,7 V (calculado a partir de R1, R2 y los carriles de ±15 V)",{"label":48,"value":49},"Igualdad entre carriles","Determinada por la tolerancia de R4 y R5 (1% en el esquema)",[51,52,53,54],"Alimentación bipolar para circuitos con amplificadores operacionales y de instrumentación","Fuentes de alimentación de preamplificadores y mezcladores de audio","Equipos de prueba analógicos que necesitan carriles simétricos","Fuentes de laboratorio de ±15 V",[56,61,65,70],{"title":57,"trap":58,"solution":59,"severity":60},"Ambos reguladores en un mismo disipador a masa","Ninguna lengüeta está en COMMON.
