The recommended layout and placement for the TPS3824-25DBVR 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. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note 'TPS3824 Layout and Placement Guidelines' for more information.
The input capacitor should be a low-ESR ceramic capacitor with a value of 1-10uF, and the output capacitor should be a low-ESR ceramic capacitor with a value of 1-22uF. The capacitor values and types should be chosen based on the specific application requirements and the output voltage ripple and noise requirements.
The maximum input voltage that the TPS3824-25DBVR can handle is 6.5V. Exceeding this voltage may cause damage to the device.
The output voltage of the TPS3824-25DBVR 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 = 2.5V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
The quiescent current of the TPS3824-25DBVR is typically 50uA, but it can be as low as 20uA in shutdown mode.
