LT1521IST-3.3#PBF Frequently Asked Questions (FAQ)
-
The LT1521 can handle input voltages up to 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
-
To ensure a stable and accurate output voltage, make sure to use a stable input voltage, choose the correct output capacitor value, and minimize noise and ripple on the input and output lines.
-
The minimum input voltage required for the LT1521 to function properly is 3.5V, but it's recommended to keep it above 4V for optimal performance.
-
The LT1521 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability.
-
The output voltage of the LT1521 can be calculated using the formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage (typically 2.5V).
