The maximum input voltage that can be applied to the LP38855S-1.2 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the distance between the input and output pins.
The minimum input voltage required for the LP38855S-1.2 to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance and to ensure the output voltage is within the specified tolerance.
The LP38855S-1.2 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.
The output voltage of the LP38855S-1.2 is fixed at 1.2V, but it can be adjusted using an external resistor divider network. The output voltage can be calculated using the formula: Vout = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
