Additional Details

The CJ7815 requires a minimum input voltage slightly higher than its output voltage (typically around 17.5V to 20V) to function correctly. A heat sink is often necessary when operating at higher currents to dissipate heat and maintain optimal performance. The device is commonly packaged in a TO-220 package, which is easy to mount and provides good thermal conductivity when properly attached to a heat sink. The operating temperature range typically spans from 0°C to +125°C.
