Hi, I need to power a 5v ht1621 LCD from 4*AA batteries. This works directly from the ~6 battery supply but the circuit also has a l293dd driven stepper motor which when turned on, dimms the lcd. This is all controlled by a pic16f1847 which uses a 3.33v 1117 LDO regulator.
The PIC can work from 5v so I thought I would replace the 3.3v LOD with a 5v one.
However
From what I understand, a 5v output LDO requires an input of 5v + dropout voltage. This fits within 6v from the batteries but what...
