Original question:

LM2940T-8.0/NOPB output problem

LM2940C: Output capacitance ESR requirement at what frequency?

Part Number: LM2940C

Hello, 

I see LM2940C specifies a very specific ESR window of stability, though i don't a frequency specified?  At what frequency is output capacitor ESR supposed to be within the specified limits since caps have different ESR at different frequency's?

Thanks
