FAQ's

Is it necessary to consider the effect of the FB pin current when choosing the resistor to set the output voltage?
- Strictly speaking, there is such an effect, but the resistance value should be of the order (number of digits) of the component value recommended on the data sheet. The output voltage is determined as a voltage ratio; if the recommended value is 24 kΩ + 30 kΩ, then the setting should be adjusted using a resistance of kΩ order.
