I was reading the datasheet on my ATTiny13, and noticed the following
ABSOLUTE MAXIMUM ratings:
Maximum Operating Voltage 6.0V
DC Current Vcc and GND pins: 200 mA
I was planning on powering my device with 4 1.2 NiMH batteries. Do I
still need a 78L05 voltage regulator, or can I skip that? (I've got
one just in case, but wondering if it's necessary with 4.8V
nominal...)
Why the restriction on the DC current input? Won't the device just
suck as much current as it needs? Or should I put a resistor there in
series with Vcc...? R=V/I = 5.0V / 0.2A = 25 ohms?
Thanks,
Michael
