TPS74401RGWR Frequently Asked Questions (FAQ)

  • The TPS74401RGWR can handle input voltages up to 12V, but it's recommended to operate within the specified input voltage range of 2.7V to 10V for optimal performance.

  • To ensure stability, it's essential to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and maintain a minimum output load of 1mA.

  • The TPS74401RGWR can provide up to 1A of output current, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.

  • The output voltage of the TPS74401RGWR can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.24V x (1 + R1/R2).

  • The EN (enable) pin is used to turn the regulator on or off. To enable the regulator, connect the EN pin to a logic high (VIN or higher). To disable the regulator, connect the EN pin to a logic low (GND).
