AZ1117CH-3.3TRG1 Linear Voltage Regulator IC Positive Fixed 1 Output 1A SOT-223-3
The DIODES™ AZ1117C is a low dropout three-terminal regulator optimized for a low voltage where transient response and minimum input voltage are critical. The device provides current-limit and thermal-shutdown features. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy of within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.
The AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V fixed output voltage versions and an ADJ output voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors.
The AZ1117C is available in the industry-standard TO252-2 Series (including TO252-2 (3), TO252-2 (4), and TO252-2 (5)), SOT89, and SOT223 packages.
