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). 2. Adding capacitor Cn enables external noise suppression and ripple rejection to be improved. However, attention should be given to system stability (phase margin). 3. To ensure operational stability, CIN, COUT, and Cn should be placed as close to the IC as possible. 4. When the strobe (STB) pin is open, output is turned on by internal bias. When the strobe function is not used, the STB pin should be connected to GND to complete strobe operation. 5. When VIN is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.

(2) Increasing VOUT VOUT can be raised by externally connecting a resistor RB between the Cn and GND pins.
