Lm3915 Calculator Updated Here

In , if you are using a high supply voltage (e.g., 12V) and 20mA per LED, the chip can get very hot. The Fix: Drop the LED supply voltage ( VLEDcap V sub cap L cap E cap D end-sub

The update tells you the power dissipation difference. In Dot mode, only one LED is on at a time. In Bar mode, all 10 LEDs could be on simultaneously. The new calculator calculates total system current and warns you if your 7805 regulator will overheat. In , if you are using a high supply voltage (e

The formula is:
