The maximum input voltage that can be applied to the LM317MDT-TR is 40V. Exceeding this voltage can cause damage to the device.
To ensure stability and prevent oscillations, a minimum output capacitance of 1uF is recommended, and the input capacitor should be at least 10uF. Additionally, the output voltage should be decoupled with a capacitor of at least 10uF.
The minimum load current required for the LM317MDT-TR to regulate properly is 3.5mA. If the load current is less than this, the output voltage may not be regulated accurately.
No, the LM317MDT-TR is designed to regulate positive voltages only. If you need to regulate a negative voltage, you should use a negative voltage regulator such as the LM337.
The output voltage of the LM317MDT-TR can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V).
