copyright ? anpec electronics corp. rev. a.9 - apr., 2003 apl5301/2 www.anpec.com.tw 10 the minimum input-output voltage difference (dropout) determines the lowest usable supply voltage. in bat- tery-powered systems, this will determine the useful end-of-life battery voltage. because the apl5301/2 use a p-channel mosfet pass transistor, the drop- out voltage is a function of drain-to-source on-resis- tance (r ds(on) ) multiplied by the load current. the apl5301/2 load-transient response graphs in typi- cal characteristics show the transient response. a step change in the load current from 1ma to 50ma at 1us will cause a 60mv transient spike. larger output capacitor and lower esr can reduce transient spike. application information capacitor selection and regulator stability the apl5301/2 use at least a 1uf capacitor on the input, and this capacitor can be aluminum, tantalum or ceramic capacitor. the input capacitor with larger value and lower esr provides better psrr and line- transient response. the output capacitor also can use aluminum, tantalum or ceramic capacitor, and a mini- mum value of 1uf and esr above 0.06 ? is recommended. the curve of the stable region in typi- cal characteristics shows the appropriate output ca- pacitor esr for different load current stable operation. a larger output capacitor can reduce noise and im- prove load-transient response, stability, and psrr. note that some ceramic dielectrics exhibit large ca- pacitance and esr variation with temperature. when using this capacitor, a minimum 2.2uf or more may be required to ensure the stability at low temperature operation. use a bypass capacitor at bp pin for low output nvise. increasing the capacitance will slightly decrease the output noise, but increase the start-up time. (see shutdown exit delay and output noise vs.bypass capacitor graph in the typical characteristics) load-transient considerations input-output (dropout)voltage reverse current protection the apl5301/2 have an internal reverse protection, it does not need an external schottky diode to connect the regulator input and output. if the output voltage is forced above the input voltage by more than 11mv, the ic will be shutdown and the ground pin current is below 0.1ua. current limit the apl5301/2 have a current limit protection. the ouptut voltage will drop close to zero volt, when load current reaches the limit, and then the load current will be limited at 50ma after output voltage is below 0. 7v. when the load current back to the value where limiting started, the output voltage and current will re- turn to normal value. when output is shorted to ground, the apl5301/2 will keep short circuit current at 150ma .
copyright ? anpec electronics corp. rev. a.9 - apr., 2003 apl5301/2 www.anpec.com.tw 11 thermal protection limits total power dissipation in the device. when the junction temperature exceeds t j =+150 , the thermal sensor generates a logic sig- nal to turn off the pass transistor and allows ic to cool. when the ic?s junction temperature is down by 10 , the thermal sensor will turn the pass transistor on again, resulting in a pulsed output during continu- ous thermal protection. thermal protection is designed to protect the apl5301/2 in the event of fault conditions. for continuous operation, do not exceed the absolute maximum junction temperature of t j =+150 . operating region and power dis- sipation the thermal resistance of the case to circuit board, and the rate of air flow all control the apl5301/2?s maximum power dissipation. the power dissipation across the device is p d = i out (v in -v out ) and the maxi- mum power dissipation is: p dmax = (t j -t a ) / ( jc + ca ) where t j -t a is the temperature difference between the junction and ambient air, jc is the thermal resis- tance of the package, and ca is the thermal resis- tance through the printed circuit board, copper traces, and other materials to the ambient air. the gnd pin of the apl5301 and apl5302 that the packages ard sot-23-5, sot-89-5 and sop-8 pro- vide an electrical connection to ground and channel- ing heat away. if power dissipation is large, connect the gnd pin to ground using a large pad or ground plane, can improve the problem of over heat of ic. thermal protection
