I'm looking to move from a Linear Regulator to a Switching Regulator with as little fuss as possible. I have found this (
TLE 4271) unit from Mouser and would like some insight.
I am using a PIC 16F series chip. The input voltage to the regulator is 14~15.5 and the output will be 5 volts drawing at most 150mA.
I really don't know if I need Pins 2, 3, or 6 or how to bypass them if possible.
1) The reset (pin 3) appears to be internally connected to the output. Anything else need to be done?
2) Not sure why I would need the Watchdog Input - do I need to connect it to something?
3) Can someone explain what INHIBIT (pin 2) means?
In a nutshell, I would like to see if the circuit below would satisfy my needs and what to do with those pins (2,3,6).
Typical Circuit and Pin Layout at bottom.
Thanks,
SF
