Q esr Q 300m ? on the output ensures stability. higher capacitance values help to improve line and load transi ent response. the output capacitance may be increased to keep low undershoot and ove rshoot. output capacitor must be placed as close as possible to out and gnd pins. adjustable operation adjustable operation is not available in the sot223 to252 and so-8ep package. the ap7361 provides output voltage from 0.8v to 5.0v through external resistor divider as shown below. 1uf in gnd en out enable adj r2 r1 4.7uf v in v out ap7361 adjustable output the output voltage is calculated by: ? ? ? ? ? ? ? ? ? ? 2 r 1 r 1 ref v out v where v ref = 0.8v (the internal reference voltage) rearranging the equation will give the following that is used for adjusting the output to a particular voltage: ? ? ? ? ? ? ? ? ? ? 1 ref v out v 2 r 1 r to maintain the stability of the internal reference voltage, r 2 need to be kept smaller than 80k ? .
