ts9001 series 300ma cmos ldo with enable 3/6 version: c12 detail description description the ts9001 series of cmos regulators contain a p-mo s pass transistor, voltage reference, error amplifi er, over current protection, thermal shutdown and short circ uit protection. the ts9001 series switches from voltage mode to cur rent mode when the load exceeds the rated output cu rrent. this prevents over stress. the ts9000 also incorpor ates current fold-back to reduce power dissipation when the output is short circuit. this feature becomes activ e when the output drops below 1.05v, and reduces th e current flow by 65%. full current is restored when the volt age exceeds 0.95v. the internal p-channel pass transistor receives dat a 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 t emperature exceeds 150 o c, or the current exceeds 300ma. during thermal shu tdown, the output voltage remains low. normal operation is restored when the junction temperature drops below 120 o c. enable the chip enable pin normally floats high. when acti vely, pulled low, the pmos pass transistor shut off , and all internal circuits are powered down. in this state, the quiescent current is less than 5ua. this pin be haves much like an electronic switch. external capacitor the ts9001 series is stable with an output capacito r to ground of 2.2uf 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 s hould be larger than 0.1uf to have a beneficial effect. a third capacitor can be connected between the bypa ss pin and ground. this capacitor can be a low cost polyester film variety between the value of 1~10nf. a larger capacitor improves the ac ripple rejection, but als o makes the output come up slowly. this soft turn-on is desir able in some applications to limit turn-on surges. all capacitors should be placed in close proximity to the pins. a quiet ground termination is desira ble.
