The maximum input voltage 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 PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and GND pins.
The minimum input voltage is 2.5V, but it's recommended to keep it above 3V for optimal performance.
The LP3961EMP-1.8/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to prevent overheating and ensure reliability.
The output voltage is fixed at 1.8V, but you can adjust it by using an external resistor divider network. Refer to the datasheet for the calculation formula and example circuits.
