ST1S40IDR Frequently Asked Questions (FAQ)
-
A good PCB layout for the ST1S40IDR involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces to reduce parasitic inductance and capacitance.
-
To ensure stability, it's essential to follow the recommended output capacitor selection and layout guidelines, and to ensure that the output capacitor has a low equivalent series resistance (ESR) and a high ripple current rating.
-
The ST1S40IDR can handle a maximum input voltage of 18V, but it's recommended to operate within the specified input voltage range of 4.5V to 14V for optimal performance and reliability.
-
The output voltage of the ST1S40IDR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage, and R1 and R2 are the resistors in the feedback network.
-
The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is disabled, and the output voltage is turned off.
