LM1117T-3.3 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM1117T-3.3 is 15V, but it's recommended to keep it below 12V for reliable operation.
-
The LM1117T-3.3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
-
To ensure stability, use a minimum output capacitance of 10uF, and keep the distance between the output capacitor and the regulator as short as possible. Also, use a low-ESR capacitor to minimize oscillations.
-
Yes, the LM1117T-3.3 is suitable for battery-powered devices due to its low quiescent current (IQ) of 5mA. However, consider using a low-dropout regulator like the TLV703 for even lower IQ.
-
Use a TVS (transient voltage suppressor) diode or a zener diode in parallel with the input capacitor to protect the regulator from input voltage transients.
