copyright ? anpec electronics corp. rev. a.5 - aug., 2004 apl5158 www.anpec.com.tw 10 application information capacitor selection and regulator stability the apl5158 use at least a 1uf capacitor on the input. this capacitor can use aluminum, tantalum or ceramic capacitors. input capacitor with large value and low esr provides better psrr and line-transient response. the output capacitor also can use aluminum, tantalum or ceramic capacitors, and it?s minimum values is recommended 1uf, esr muse be above 0.01 ? . the curve of the region of stable c out esr vs. load current in typical characteristics shows the output capacitor esr and load current range for apl5158 stability. large output capacitor values can reduce noise and improve load-transient response, stability, and psrr. note that some ceramic dielec- trics exhibit large capacitance and esr variation with temperature. if use this capacitor, it may be neces- sary to use 2.2uf or more to ensure stability at tem- perature below -10 c. load-transient considerations the apl5158 load-transient response graphs in typi- cal characteristics show the transient response. a step change in the load current from 0.1ma to 150ma at 15u second will cause less than 10mv transient spike. large output capacitor?s value and low esr can reduce transient spike. shutdown/enable the apl5158 has an active high enable function. force en high (>1.6v) enables the regulator, en low (<0.4v) disables the regulator and enter the shut- down mode, it also causes the output voltage to dis- charge through a 500 ? resistance to ground. in shut- down mode, the quiescent current can reduce below 1ua. the en pin cannot be floating, a floating en pin may cause an indeterminate state on the output. if it is no use, connect to v in for normal operation. power ok the power ok function monitors the output voltage and drives high or low to indicate a fault. when a fault condition such as overcurrent, undervoltage, ther- mal shutdown., or dropout occurs, the power ok out- put is pulled low. the power ok output comes back when the output voltage has reached 90% of it?s nomi- nal value and with a typ. 2.5ms delay time. the power ok is an open-drain output, connect a 10k ? resis- tance to v out for typical application input-output (dropout)voltage the minimun input-output voltage differential (dropout) determines the lowest usable supply voltage. the mini- mum input voltage is 2.7v and output voltage is 1.2v, so the dropout voltage is 1.5v. reverse protection the apl5158 has a internal reverse protection, it doesn?t need a external schottky diode to connect the regulator input and output. if the output voltage is forced above the input voltage, the ic will be shut- down and the reverse output current is below 4ma , it will increase with the output voltage. the maximum allowable output voltage is 7v (see absolute maxi- mum rantings). current limit the apl5158 has a current limit protection, which senses the current flows the p-channel mosfet, and controls the output voltage. the point where limiting occurs is i out =600ma and the output voltage will be shutdown. the output can be shorted to ground for an indefinite amount of time without damaging the part.
