The maximum operating temperature range for the TPS2815PWR is -40°C to 125°C.
To ensure proper power-up and initialization, make sure to follow the recommended power-up sequence, which is to apply VCC first, followed by EN, and then IN. Also, ensure that the input voltage is within the recommended range and that the output capacitor is properly sized.
The recommended input capacitor value is 1uF to 10uF, and it should be a low-ESR ceramic capacitor, such as X5R or X7R, to minimize voltage ripple and ensure stable operation.
The output voltage of the TPS2815PWR can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.21V), and R1 and R2 are the resistors connected to the FB pin.
The maximum output current capability of the TPS2815PWR is 1.5A, but it can be limited by the thermal performance of the package and the PCB design.
