Pinout
The AZ1117D-3.3TRE1 is a low dropout (LDO) linear voltage regulator. It typically comes in a 3-pin SOT-223 package. The pin functions are as follows:
1. Pin 1 (Adjust/Ground): In the fixed version (which includes the AZ1117D-3.3), this pin is connected to ground. In the adjustable version, it acts as the adjust pin for setting the output voltage.
2. Pin 2 (Output): This is the regulated output voltage pin, delivering a fixed output of 3.3V in the AZ1117D-3.3 version.
3. Pin 3 (Input): This pin receives the unregulated input voltage, which the regulator then converts to the stable output voltage.
There's also a tab that serves as an extended ground (usually connected to pin 1) for heat dissipation. This package design is advantageous for applications requiring efficient heat management.
