The recommended PCB footprint for the SI2309CDS-T1-E3 is a 5-pin SOT23 package with a minimum pad size of 0.8mm x 0.8mm and a thermal pad size of 2.5mm x 2.5mm.
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 1uF and a maximum ESR of 1 ohm, and to place the output capacitor as close to the output pin as possible.
The maximum ambient temperature range for the SI2309CDS-T1-E3 is -40°C to 125°C, but the device can operate up to 150°C with derating.
Yes, the SI2309CDS-T1-E3 is qualified to AEC-Q100, which makes it suitable for high-reliability applications such as automotive systems.
The power dissipation of the SI2309CDS-T1-E3 can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
