ap160 600ma cmos ldo anachip corp. www.anachip.com.tw rev. 1.1 no v 22, 2004 6/9 ? detailed description the ap160 family of cmos regulators contain a pmos pass transistor, voltage reference, error amplifier, over-current protection, thermal shutdown, and short circuit protection. the p-channel pass transistor receives data from the error amplifier, over-current shutdown, short output protection, and thermal protection circuits. during normal operation, the error amplifier compares the output voltage to a precision reference. over-current and thermal shutdown circuits become active when the junction temperature exceeds 150 o c, or the current exceeds 600ma. during thermal shutdown, the output voltage remains low. normal operation is restored when the junction temperature drops below 120 o c. the ap160 switches from voltage mode to current mode when the load exceeds the rated output current. this prevents over-stress. the ap160 also incorporates current fold-back to reduce power dissipation when the output is shout-circuited. this feature becomes active when the output drops below 0.8v, and reduces the current flow by 65%. full current is restored when the voltage exceeds 0.8v. ? external capacitor the ap160 is stable with an output capacitor to ground of 2.2f or greater. it can keep stable even with higher or poor esr capacitors. a second capacitor is recommended between the input and ground to stabilize vin. the input capacitor should be larger than 0.1f to have a beneficial effect. all capacitors should be placed in close proximity to the pins. a ?quiet? ground termination is desirable.
