Additional Details

The AMS1086CD-3.3 is available in a TO-252 package. It requires minimal external components for operation, making it easy to integrate into a variety of circuits. Proper heat sinking is essential when operating at high currents to prevent overheating. The regulator is designed to be stable with ceramic output capacitors, which offer low ESR and improved performance. It is a popular choice for applications requiring a stable 3.3V supply, such as powering microcontrollers, memory chips, and other digital logic circuits. The low dropout voltage allows it to operate efficiently even with a relatively small difference between the input and output voltages.
