Diodes – AZ1117I – Industrial Temperature Range 1A Low Dropout Linear Regulator
The AZ1117I is a 1A industrial temperature range low dropout three-terminal regulator. The AZ1117I is optimized for industrial applications operating from 12V or 5V applications where transient response and minimum input voltage overheads are critical. Its trimmed bandgap reference assures tight ±1% output voltage accuracy. It provides current limit and thermal shutdown, which provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.
The AZ1117I is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed output voltage versions and, ADJ output voltage version which sets the output voltage with two external resistors.
The AZ1117I is available in the industry-standard SOT223 and TO252 power packages.
