AN78M12R

AN7800R/AN78M00R Series Positive Output Voltage Regulators with Reset pin (1A/500mA Type) s Overview The AN7800R and the AN78M00R series are the fixed positive output voltage regulators with reset pin. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. Three types of output voltage, 5V, 9V and 12V, are available for the AN7800R series, and four types, 5V, 8V, 9V and 12V, are available for the AN78M00R series. They can be used in power circuits with current capacitance 1A/500mA. ON/OFF of output voltage can be controlled by the reset pin. 9.6 – 0.1 ø 3.1 4.0 + 0.5 Unit:mm 12.5max. 0.7±0.2 2.3 2.3 2.3 3.3max. 9.0min. 3–1.0 1.8 2.0 0.5±0.1 1.5 1.3 s Features No external components Maximum output current :1A (AN7800R) 500mA (AN78M00R) Output voltage :5V, 9V, 12V (AN7800R) :8V (AN78M08R) Short-circuit current limiting built-in Thermal overload protection built-in Output transistor safe area compensation ON/OFF of output voltage can be controlled by reset pin. 4-pin SIL Plastic Package with Fin (SSIP004-P-0000) s Block Diagram 1 Pass Tr Q1 Current Source Current Limiter Input RSC 3 Output Reset Starter Voltage Reference + Error Amp. – 4 Thermal Protection R2 R1 2 Common s Absolute Maximum Ratings (Ta=25˚C) Parameter Input voltage Power dissipation Operating ambient temperature Storage temperature Symbol VI PD Topr Tstg Rating 35 10 *1 –20 to + 80 –55 to + 150 Unit V W ˚C ˚C *1 Follow th...
