What the AZ1117C family does
The AZ1117C is a low dropout three-terminal linear regulator designed for applications requiring low input voltage and precise transient response. This family spans fixed output versions at 1.2V through 5.0V, an adjustable ADJ version, and operates across commercial, industrial, and military temperature grades from -20°C to +125°C. Key specifications include a typical 1.35A current limit, 70dB power supply rejection ratio, and maximum quiescent current of 6mA. The device features on-chip thermal shutdown and output voltage accuracy within ±1%. It supports USB devices, PC motherboards, and DVD players, and is compatible with low ESR ceramic capacitors in TO252, SOT89, and SOT223 packages.
