600mA LOW DROPOUT LINEAR REGULATOR 600mA LOW DROPOUT LINEAR REGULATOR General Description The AP2317 is a series of low dropout three-terminal regulators with a dropout of 1.1V at 600mA output current. This product has been optimized for low voltage where transient response and minimum input voltage are critical. The AP2317 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 any combination of overload and ambient temperatures that would create excessive junction temperatures. The AP2317 is available in 2.5V and 3.3V versions. 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 AP2317 series regulators are available in the industry standard SOT-89-3, SOT-223 and TO-263-3 (for 3.3V only) power packages.
