A good PCB layout for the LMS1585ACS-1.5/NOPB should include a solid ground plane, a separate power plane for the input voltage, and a heat sink attached to the exposed pad of the IC. The layout should also minimize the distance between the input capacitors and the IC.
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the IC. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
The maximum input voltage that can be applied to the LMS1585ACS-1.5/NOPB is 15V. Exceeding this voltage may cause damage to the IC.
The output voltage of the LMS1585ACS-1.5/NOPB can be calculated using the following formula: VOUT = 1.5V * (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
The maximum output current that the LMS1585ACS-1.5/NOPB can deliver is 3A. Exceeding this current may cause overheating and damage to the IC.
