Planning tool calls.

Based on the Flux knowledge base guidance:
  • When selecting power regulators, ensure they support the total load current plus a 25% buffer. The LM7805 is rated for 1 A, so budget at least 1.25 A of headroom.
  • Consider VOUT tolerance and line regulation accuracy (±4% typical → ±200 mV) when the output rail drives sensitive circuitry.
  • Don’t forget the datasheet-specified input and output capacitors close to the regulator for stability.
Here are top LM7805 options from the Flux library:

El proyecto descrito parece ser una aplicación básica de un circuito de temporización utilizando un chip de temporizador 555, una pieza clásica de diseño de circuitos analógicos ampliamente utilizada por su versatilidad y fiabilidad.
El temporizador 555 puede configurarse para funcionar en varias formas: en modos de astable, monoestable y bistable.
  1. Modo Astable: El circuito oscila entre dos estados. Este modo se utiliza comúnmente para la generación de pulsos de clock y señales de onda cuadrada.
  2. Modo Monoestable: El circuito se activa y entra en un estado especial durante un período específico y luego vuelve al estado inicial. Se utiliza para generar retardos temporales y "one-shots".
  3. Modo Bistable: Utiliza el 555 como un flip-flop simple, con dos estados estables que se pueden conmutar mediante señales de entrada.
Dado que tu esquema no contiene conexiones eléctricas por el momento, no puedo determinar en cuál de estos modos tiene la intención de operar tu circuito.
Ten en cuenta que la implementación y el comportamiento de estas configuraciones dependen de cómo conectes componentes externos (como resistencias y condensadores) a los pines del IC 555.
