M Di ain sc te on na tin nc ue e/ d The AN77LxxM series are 3-pin, fixed positive output type monolithic voltage regulators. The AN77L05M is the 5 V output voltage type in these series. They can be used widely in power supply circuits with current capacity of up to 100 mA. It is suitable for the low-voltage equipment using batteries and consumer/industrial equipment with great fluctuation of the supply voltage. Stabilized fixed output voltage is obtained from unstable DC input voltage with using a 10 μF output capacitor. 11 types of fixed output voltage are available; 3 V, 3.5 V, 4 V, 4.5 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V and 12 V. y Minimum input/output voltage difference: 0.20 V typ. y Built-in over current limit circuit y Built-in rush current prevention circuit at input voltage rise y Built-in overheat protection circuit y Built-in input short-circuit protection circuit Applications y 3-pin positive output voltage regulator (100 mA type) Package y 3-pin Plastic Single Inline Package With Heat Sink (SIP type) Type Pl ea Ma int en an ce /D isc on tin ue y Silicon monolithic bipolar IC SFF00083BEB 3 an en CIN ue on tin isc ce /D + Error Amp. – Over heat protection 3 2 Common Pl ea Output Driver d pla inc ne lud se pla m d m es v ne ain ain foll htt isit d te t o p:/ fo /w llo dis disc nan enan wing ww wi co on ce c fo .se ng ntin tin ty e ty ur mi UR ue ued pe pe Pro co L a d t ty du n.p bo yp pe ct life an ut e d as lat cy on es cle ic. t in sta co fo ge .jp rm . /en at i o / n. int CIN : 0.33 μF COUT : 10 μF R1 : 30 kΩ R2 : 10 kΩ Ma Input Voltage Reference Starter M Di ain sc te on na tin nc ue e/ d AN77L05M Block Diagram Input short-circuit protection SFF00083BEB Pass Tr Over current limit Rush current prevention R1 R2 1 Output COUT 4 an en ue on tin isc ce /D 1 Output 2 Common GND Ground. 3 Input Input Input voltage Output Pl ea Pin name d pla inc ne lud se pla m d m es v ne ain ain foll htt isit d te t o p:/ fo /w llo dis disc nan enan wing ww wi co on ce c fo .se ng ntin tin ty e ty ur mi UR ue ued pe pe Pro co L a d t ty du n.p bo yp pe ct life an ut e d as lat cy on es cle ic. t in sta co fo ge .jp rm . /en at i o / n. int Pin No. Ma M Di ain sc te on na tin nc ue e/ d AN77L05M Pin Descriptions Type Description Output voltage SFF00083BEB 5 AN77L05M Absolute Maximum Ratings A No. Parameter Symbol Rating Unit Note Input voltage VIN 30 V *1 2 Supply current ICC 200 mA ⎯ 3 Power dissipation PD 252 mW *2 4 Operating ambient temperature Topr −30 to +85 °C *3 5 Storage temperature Tstg −55 to +150 °C *3 M Di ain sc te on na tin nc ue e/ d 1 Note) *1: The values under the condition not exceeding the above absolute maximum ratings and the power dissipation. d pla inc ne lud se pla m d m es v ne ain ain foll htt isit d te t o p:/ fo /w llo dis disc nan enan wing ww wi co on ce c fo .se ng ntin tin ty e ty ur mi UR ue ued pe pe Pro co L a d t ty du n.p bo yp pe ct life an ut e d as lat cy on es cle ic. t in sta co fo ge .jp rm . /en at i o / n. *2: The power dissipation shown is the value at Ta = 85°C.

M Di ain sc te on na tin nc ue e/ d 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 input pin and the electric charges which is charged in output capacitor COUT 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. 3 2 Input VIN Figure 1. Protection diode 1 Common CIN 0.33 μF Output COUT 10 μF Not required on tin ue 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 pin (pin 2), the IC is likely to be broken. Pl ea Equivalent series resistance (Ω) 50 Ma int en an ce /D isc 3. Capacitor for external compensation In order to secure the stability, the capacitor of 10 μF 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 the 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 within the recommended range specified in “Figure 2" should be used. 40 VOUT 30 20 10 0 Recommended range 20 0 40 60 80 100 Output current IOUT (mA) 200 IOUT (mA) Figure 3.
