Technical Notes on the Components Selection

• In this device, phase compensation is provided to secure stable operation even when the load current

varied. For this purpose, connect 0.22 μF or more output capacitors (COUT1, COUT2) between the VOUT

and GND pin with shortest-distance wiring. In case of using a tantalum type capacitor and the ESR

(Equivalent Series Resistance) value of the capacitor is large, the output might be unstable. Evaluate the

circuit including consideration of frequency characteristics.

• Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or

unstable operation may result. Connect a 0.22 μF input capacitor (CIN) between the VDD and GND pins

with shortest-distance wiring. Refer to Typical Application Circuit.
