Peripheral Settings for Pins and Precautions

1. VCC pin

Insert capacitors with a capacitance from 0.33 µF to 1000 µF between the VCC and GND pins.

The capacitance varies with the application. Be sure to design the capacitance with a sufficient margin.

2. Capacitors for stopping oscillation on output pins

Capacitors for stopping oscillations must be placed between each output pin and the GND pin. Use a capacitor within the

capacitance range of 0.1 µF and 1000 µF. Since oscillations do not occur even for ESR values from 0.001

Ω to 100 Ω, a

ceramic capacitor can be used. Abrupt input voltage and load fluctuations can affect output voltages. Output capacitor

capacitance values should be determined after sufficient testing of the actual application.

θja = 104.2 °C / W

→ -9.6 mW / °C

25 °C = 1.2 W

→ 85 °C = 0.624 W
