AZ1117C数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The AZ1117C is a low dropout three-terminal regulator.
\t
\t\tThe AZ1117C has been optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.
\t
\t\tThe AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed output voltage versions and 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.
\t
\t\tThe AZ1117C is available in the industry-standard TO2522 (3), TO2522 (4), and TO2522 (5), SOT89-3L and SOT223 power packages.
