The recommended layout and placement for the TPS3801J25DCKR involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, it is recommended to use a low-ESR capacitor for the input capacitor and a low-ESL capacitor for the output capacitor.
The choice of input and output capacitors for the TPS3801J25DCKR depends on the specific application requirements. In general, a low-ESR capacitor with a value of 1-10uF is recommended for the input capacitor, and a low-ESL capacitor with a value of 1-22uF is recommended for the output capacitor. The capacitor values and types should be chosen based on the specific requirements of the application, such as the input voltage, output voltage, and output current.
The maximum input voltage that the TPS3801J25DCKR can handle is 28V. Exceeding this voltage may cause damage to the device.
The output voltage of the TPS3801J25DCKR can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage can be calculated using the formula: Vout = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
The quiescent current of the TPS3801J25DCKR is typically around 50uA. This is the current consumed by the device when it is in standby mode.
