電源良好信號 Power good signal

The system shall have an active high TTL compatible signal capable of sinking 1mA and

sourcing 100uA. The signal shall become active within 100 to 500 ms from the instant +5V output

reaches a steady state level within the specified regulation limits. It shall become inactive at least

1 ms before +5V drops to below the lower regulation limit.
