The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input voltage ripple and improve overall system stability.
To ensure proper power-up and initialization, connect the EN pin to a logic-high voltage (e.g., VCC) and ensure the input voltage (VIN) is within the recommended operating range. Also, ensure the output capacitor is properly sized and connected to the output pin.
The maximum output current capability of the TPS3823-25DBVT is 150mA. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
The output voltage of the TPS3823-25DBVT is fixed at 2.5V. If a different output voltage is required, an external resistor divider network can be used to adjust the output voltage, but this may affect the overall efficiency and stability of the regulator.
The thermal shutdown temperature of the TPS3823-25DBVT is typically around 150°C to 160°C. When the junction temperature exceeds this threshold, the regulator will shut down to prevent damage.
