The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor can be used to improve noise rejection and input ripple reduction.
To ensure stability, use a minimum output capacitor of 2.2uF with an ESR of 0.1Ω to 10Ω. Additionally, place the output capacitor close to the output pin and use a low-ESR capacitor to minimize oscillations.
The maximum dropout voltage for the TPS7301QDG4 is 1.4V at an output current of 1A. This means that the input voltage must be at least 1.4V higher than the output voltage to maintain regulation.
The TPS7301QDG4 is rated for operation up to 125°C. However, the device's power dissipation and junction temperature must be considered to ensure reliable operation. Use the thermal resistance and power dissipation calculations provided in the datasheet to determine the maximum operating temperature for your specific application.
The power dissipation of the TPS7301QDG4 can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. Use the values provided in the datasheet to calculate the power dissipation for your specific application.
