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.
