The maximum input voltage that can be applied to the LM120H-15/NOPB is 35V, but it's recommended to keep it below 25V for optimal performance and to prevent overheating.
The LM120H-15/NOPB has a maximum operating junction temperature of 150°C, but it's recommended to keep it below 125°C for optimal performance and reliability. You may need to use a heat sink or thermal management system to keep the temperature within the recommended range.
To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF and a maximum ESR of 5 ohms. You can also add a bypass capacitor between the input and ground pins to improve noise rejection and stability.
The LM120H-15/NOPB is a linear voltage regulator, not a switching regulator, so it's not suitable for switching power supply designs. It's designed for low-dropout, low-noise applications where a high degree of regulation is required.
The power dissipation of the LM120H-15/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. Make sure to consider the thermal resistance and maximum junction temperature when calculating the power dissipation.
