APPLICATION INFORMATION

Setting the Output Voltage The output voltage can be adjusted by changing the values of the external resistor divider. Use the following equation to determine these values: ⎛ +×= 2R 1R1V5.0VOUT Typically R1 + R2 are recommended to be less than 100kΩ. In Figure 2, C2 is added for improved transient response.
