A good PCB layout for the REF3433MDBVTEP involves keeping the input and output traces separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure proper decoupling, place a 10uF ceramic capacitor between the VIN pin and the GND pin, and a 100nF ceramic capacitor between the VOUT pin and the GND pin. Additionally, use a 1uF ceramic capacitor between the VIN pin and the VOUT pin.
The REF3433MDBVTEP can provide a maximum output current of 50mA. However, it's recommended to limit the output current to 30mA to ensure optimal performance and prevent overheating.
The output voltage of the REF3433MDBVTEP can be adjusted by using an external resistor divider network between the VOUT pin and the ADJ pin. The output voltage can be calculated using the formula: VOUT = 1.24V x (R1 + R2) / R2.
The thermal shutdown temperature of the REF3433MDBVTEP is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 130°C.
