Pin 1 - IN (Input): This is the input pin where you supply the input voltage. The voltage supplied to this pin should be within the range of 2.5V to 5.5V. The input is used to power the internal circuitry of the voltage regulator and regulate the output accordingly. Pin 2 - GND (Ground): This pin is connected to the ground (0V) of the system to establish a common reference point. It is essential for completing the electrical circuit and ensuring proper operation. Pin 3 - EN (Enable): This pin is used to control the enable state of the device. A high signal (logic 1) on this pin enables the voltage regulator to output the regulated voltage. A low signal (logic 0) disables the regulator and puts it into a low-power shutdown mode. Pin 4 - OUT (Output): This is the output pin where the regulated voltage is provided. The voltage is typically 3.3V or 1.8V depending on the version of the TLV70233 being used. This voltage is used to power downstream components or circuits requiring a stable regulated voltage. Pin 5 - FB (Feedback): The FB pin is used in conjunction with an external resistor divider network to set the output voltage. Feedback is provided to the internal control loop to maintain the desired output voltage.FAQ (Frequently Asked Questions) about TLV70233DBVR:
