I build a voltage regulator circuit for esp8266-01 based on 1117 regulator. As per datasheet for fixed voltage output 0.1uf capacitor should be at Vin and 10uf on Vout. My question is why on 1117 is oposite of other regulator circuits that 0.1uf capacitor is always at Vout and bigger capacitor is a…
