Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. TO-220 1 D-PAK 1 1. Input 2. GND 3.

The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage. (2) CI is required if regulator is located an appreciable distance from power Supply filter. (3) CO improves stability and transient response.
