AP2318A

600mA LOW DROPOUT LINEAR REGULATOR 1A ULDO REGULATOR WITH ENABLE General Description Features Data Sheet AP1117M AP2318A The AP2318A is a series of ultra low dropout regulators optimized for low voltage applications where transient response and minimum input voltage are critical. The AP2318A provides current limit and thermal shutdown function. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1.5%. On-chip thermal shutdown provides protection against any combination of overload and ambient temperatures that would cause excessive junction temperatures. The AP2318A has adjustable version, which can set the output voltage through two external resistors. The AP2318A is available in the standard DFN-3x3-8 and PSOP-8 packages. · Wide Operating Voltage Range: 2.5V to 12V · Output Voltage Accuracy: ±1.5% · On-chip Thermal Shutdown · ESD Rating: 3000V (Human Body Model) 600V (Machine Model) · Operation Junction Temperature: -40oC to 125oC Applications · Notebook · USB Device · Add-on Card · DVD Player · PC Motherboard DFN-3x3-8 PSOP-8 Figure 1.
