an77l05m 10 sff00083beb ? usage notes 1. input short-circuit protection circuit for the conventional panasonic 3-pin regulators (such as of the an80xx series), when dc input pin (pin 3) is short-circuited with gnd pin (pin 2) in the normal operation condition, the potential of output pin (pin 1) becomes higher than that of dc inpu t pin and the electric charges which is charged in output capacitor c out flows in the input side, having resulted in the breakage of elements. in the above case, the common silicon diode is connected as shown in the following figure (the dotted line). however, for the an77lxxm series, since the protection circuit, which protects the elements from the discharging current, is incorporated in the internal circuit, the protection diode is not required. figure 1. protection diode figure 2. esr recommended range figure 3. over current limit control 0 200 i out (ma) v out 50 40 30 20 10 0 20 40 60 80 100 recommended range output current i out (ma) equivalent series resistance ( ) 2. short-circuit between the output pin and the gnd pin because there is no in-built protection circuit in the an77lxxm series, they have the drooping characteristics as shown in "figure 3". when your use under a high voltage happens to cause any short-circuit between the output pin (pin 1) and the gnd pi n (pin 2), the ic is likely to be broken. 3. capacitor for external compensation in order to secure the stability, the capacitor of 10 f is required in the output side and it should be added as near to output pin (pin 1) and gnd pin (pin 2) as possible. when it is used under low temperature, oscillation may occur due to the decrease of th e aluminum electrolytic capacitor's capacitance and an increase of esr. for the an77lxxm series, it is recommended that the tantalum capacitor or aluminum electrolytic capacitor whose equivalent serial resistance with temperature characteristics withi n the recommended range specified in ?figure 2" should be used. not required 2 1 c out input common output 3 0.33 f 10 f v in c in maintenance/ discontinued maintenance/discontinued includes following four product lifecycle stage. planed maintenance type maintenance type planed discontinued typed discontinued type please visit following url about latest information. http://www.semicon.panasonic.co.jp/en/
