LT1521IST-3.3#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT1521IST-3.3#PBF is 15V. Exceeding this voltage may damage the device.
-
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
-
The minimum input voltage required for the LT1521IST-3.3#PBF to operate is 3.5V. Operating the device below this voltage may affect its performance and stability.
-
The LT1521IST-3.3#PBF is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
-
To reduce the noise and ripple in the output voltage, it is recommended to add a 10uF capacitor between the VOUT and GND pins, and a 10nF capacitor between the VIN and GND pins. Additionally, using a low-ESR output capacitor can also help reduce the noise and ripple.
