Package

The AZ1117H-3.3TRE1 is a low dropout (LDO) linear voltage regulator. It is typically available in a surface-mount package type, such as the SOT-223 (TO-261) package, which is commonly used for power management ICs due to its compact size and efficient heat dissipation capabilities.

Pinout

The AZ1117H-3.3TRE1 is a voltage regulator from Diodes Incorporated, specifically a low dropout (LDO) linear regulator. It typically comes in a 3-pin package, such as the SOT-223. Here is a brief overview of its pin count and function:
1. Pin 1 (Adjust/Ground): For the fixed output voltage version like the 3.3V, this pin serves as the ground. For the adjustable version, this is used to set the output voltage via external resistors.

2. Pin 2 (Output): This is the output pin that provides the regulated voltage, which is 3.3V for the AZ1117H-3.3TRE1.
3. Pin 3 (Input): This pin is connected to the input voltage source, which should be higher than the desired output voltage by at least the dropout voltage to ensure proper regulation.
The AZ1117H-3.3TRE1 is used in various applications to provide a stable 3.3V output from a higher input voltage with low dropout characteristics, making it ideal for powering digital circuits and other low-power applications.
