ame rev.d.06 13 ame8818 low dropout 300ma cmos regulator n detailed description n circuit limit n shutdown mode n capacitor selection and regulator stability n thermal-overload protection n psrr and operation from sources other than batteries thermal-overload protection limits total power dissipation in the ame8818. when the junction temperature arrive t j = 160 o c approximately, the thermal sensor signals the shut- down logic, turning off the pass transistor and allowing the ic to cool. use a 1 m f capacitor on the ame8818 input and a 1 m f capacitor on the out. larger input capacitor val- ues and lower esr provide better supply noise rejec- tion and line transient response. to reduce output noise and improve load transient voltage dips, use larger output capacitors up to 4.7 m f. for stable op- eration over the full temperature range with load cur- rents up to 300ma, input and output capacitors should be a minimum of 1 m f by x7r. note that some ceramic dielectrics large capacitance and esr variation with temperature. with dielectrics such as z5u and y5v, it may be necessary to use 2.2 m f or more for up to 300ma load current to ensure stability at temperatures below -10 o c. with x7r or x5r dielectrics, 1 m f is sufficient at all operating tem- peratures. these regulators are optimized for ceramic capacitors. tantalum capacitors are not recommended. bypass capacitor can be in between 0.1 m f~0.001 m f. a larger capacitor improves ac ripple rejection, but also make the output come up slowly. the ame8818 is low-dropout, low quiescent-current linear regulator designed primarily for battery-powered applications. it is available with present output voltage ranging from 1.2v to 4.5v, and can supply loads up to 300ma. the ame8818 has enable-control-pin. drive en low to shut- down out. drive en to shutdown the entire chip, reducing supply current to 5 m a. connected en to logic-high or in for normal operation. the ame8818 contains current limiters which monitor and control the pass transistor's gate voltage, limiting the guar- anteed maximum output current to 330ma minimum. the output can be shorted to ground for an indefinite time without damaging the part. the ame8818 is designed to deliver low-dropout voltage and low quiescent currents in battery-powered system. power-supply rejection ratio is 60db (typ.) at 1khz. when operating from sources other than betteries, psrr and tran- sient response can be improved by increasing input, output and bypass capacitors(see psrr vs frequency curve). n adjustable version the adjustable version uses external feedback re- sistors to generate an output voltage anywhere from 0.98v to 4.5v. v adj is trimmed to 0.98v and v out is given by the equation: v out = v adj ( 1 + r1 / r2 ) feedback resistors r1 and r2 should be high enough to keep quiescent current low, but increasing r1 + r2 will reduce stability. in general, r1 and r2 in the 10's of k w will produce adequate stability, given reason- able layout precautions. to improve stability charac- teristics, keep parasitics on the adj pin to a mini- mum, and lower r1 and r2 values.
