Voltage generation circuit, LIN bus control chip and micro-processing chip

According to the voltage generation circuit, the LIN bus control chip and the micro-processing chip, the output voltage can be stabilized through the reverse breakdown characteristic of a Zener diode and the circuit characteristics of reverse bias voltage under different conditions in combination with the sampling and voltage adjusting functions of a feedback branch, meanwhile, a first transistor adopts an enhanced transistor, and the output voltage can be stabilized through the enhanced transistor. And the effective value of the output voltage can be further improved. Meanwhile, compared with the prior art, the method has the advantages that the expected function of the low-dropout linear voltage regulator is achieved by changing device type selection, and under the condition that the expected function is achieved, the circuit structure is simplified, the number of applied components is reduced, and the circuit complexity and cost are reduced. 本申请提供一种电压产生电路、LIN总线控制芯片及微处理芯片，通过齐纳二极管的反向击穿特性以及反向偏压在不同条件下的电路特性，结合反
