The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve stability.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and add a 10nF to 100nF capacitor between the VOUT and GND pins. Additionally, ensure that the output capacitor is within the recommended range of 1uF to 10uF.
The maximum output current of the TPS60400DBVR is 50mA. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
The TPS60400DBVR is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. It's recommended to derate the output current and ensure proper thermal management to ensure reliable operation.
The output voltage of the TPS60400DBVR is set by the resistor divider network between the VOUT and GND pins. The output voltage can be calculated using the formula: VOUT = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
