This boggles me, which isn't hard since i'm new to electronics, but i would like to understand what's going on.
I have a 7805 voltage regulator connected to a 12v battery(Pin1:12v,Pin2:GND,Pin3:5V). It outputs 5v perfectly but when i feed the 5v to pin 16 of a L293D(and Pin13 to GND) the voltage drops to around 3v. Adding a 10uF capacitor(5V side of 7805) seems to solve the issue but i'm not sure i understand why.
Can anyone give me some insight ?
