Additional Details

External capacitors are typically required at the input and output to ensure stability and optimal performance. The input capacitor helps to filter out noise and voltage variations from the input supply, while the output capacitor helps to maintain a stable output voltage during load changes. The input voltage must be a few volts more negative than the desired output voltage for proper regulation. Consult the manufacturer's datasheet for specific application notes, recommended component values, and thermal considerations.
