How to Use the CA1235 Module
Using the CA1235 module is straightforward. The module typically has four pins: input voltage (VIN), ground (GND), output voltage (VOUT), and an optional enable (EN) pin. To adjust the output voltage, a resistor divider is connected between the output and the feedback (FB) pin. The output voltage can be set using the following formula:
Vout = 1.25V × (1 + R2/R1)
Where R1 and R2 are the resistors in the feedback network. This allows for precise control over the output voltage, making the CA1235 module highly customizable.
For users who prefer a fixed output, pre-set versions of the module are also available, such as the CA1235 1.8V, CA1235 3.3V, and CA1235 5V models. These fixed-output modules are ideal for applications where a specific voltage is required without the need for external components.
