I am trying to run a ESP-01 with a PIR sensor powered by an 18650 3.7 V battery
I have used:
- HT7133-1 LDO regulator 3.3V
- 1000uF 10V Capasitor
- 100nF Ceramic Capasitor
When the switch is off voltage is stable at 3.3V but as soon as I turn on the ESP-01 voltage starts to drop gradually to around 1.5 volts and ESP switches off. I am not experienced I could use any help thanks in advance.
