To ensure operational stability, CIN and COUT should be placed as close to the IC as possible. 2. Because the output capacitor COUT is set at over 100 µF to prevent oscillation at low temperatures, a capacitor that exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor). 3. When VIN is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.
