in my other project which is battery operated (6V,9V,12V) but i want 5v for my ckt. my voltage regulator 7805 itself is eating 3.2mA which is draining battery to early.
while the PT6302 does not meet what you need, I am sure other Power Trends products will. The PT6302 which I use has a shutdown current of 100uA. Erik |
