PRODUCTION DATA.
The output voltage is set using the feedback pin and a resistor divider connected to the output as shown in 代表的なアプリケーション回路. The feedback pin voltage 0.765 V, so the ratio of the feedback resistors sets the output voltage according to Equation 3:
Typically R2 is given as 100 Ω to 10 kΩ for a starting value. To solve for R1 given R2 and VOUT, use Equation 4:
