LMZ14203TZE-ADJ/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation and to prevent damage to the internal circuitry.
-
The output voltage can be adjusted by connecting a resistor divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.25V x (1 + R1/R2).
-
The minimum input voltage required for the LMZ14203TZE-ADJ/NOPB to operate is 7.2V, but it's recommended to keep it above 8V for reliable operation and to ensure that the output voltage is within the specified tolerance.
-
The LMZ14203TZE-ADJ/NOPB is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
-
To ensure stability, it's recommended to use a minimum output capacitance of 10uF with an ESR of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm. It's also important to follow the recommended PCB layout guidelines to minimize parasitic inductance and capacitance.
