The is a series of low dropout three-terminal regulators with a dropout 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.

Low Dropout Voltage: at 600mA Output Current Output Noise from 10KHz: 0.003% PSRR at IOUT=300mA and f=120Hz: 75dB Output Voltage Accuracy: � 1% On-chip Thermal Shutdown Maximum Quiescent Current: IQMAX=5mA ESD (Human Body Model): 3.5KV Operation Junction Temperature: to 125oC

For Adjustable Output, disconnect A1 and A2, connect B For Fixed Output, connect A1 and A2, disconnect A1 A2
