| 78XX Description This series of fixed-voltage monolithic integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. Each of these regulators can deliver up to1.5 A of output current. The internal limiting and termal shutdown features of these regulators make them essentially immune to overload. Features 3-Terminal Regulators Output Current Up to 1.5 A No External Components Internal Thermal Overload Protection High Power Dissipation Capability Internal Short-Circuit Current Limiting Output Transistor Safe-Area Compensation = = Package TO-220 (top view) = Internal Block Digram Package BEIJING ESTEK ELECTRONICS CO.,LTD 1 78XX Absolute Maximum Ratings over operating temperature range (unless otherwise noted) Parameter Input voltage 7824 7827 All others Maximum 40 35 2 15 0 to 150 -65 to 150 260 Units V Continuous total dissipation at 25 C free-air temperature Continuous total dissipation at (or below) 25 C case temperature Operating free-air, case, or virtual junctions temperature range Storage temperature range Lead temperature 1.6 mm (1/16 inch) from case for 10 seconds W C Recommended Operating Conditions Parameter 7805 7806 7808 7885 7809 Input voltage VI 7810 7812 7815 7818 7820 7824 7827 Min 7 8 10.5 10.5 11.5 12.5 14.5 17.5 21 23 27 30 0 Max 25 25 25 25 27 28 30 30 33 36 38 40 1.5 125 C Units V Output current, IO A Operating virtual junction temperature, TJ Device Selection Guide Device 7805 7806 7808 7885 7809 7810 7812 7815 7818 7820 7824 7827 Output Voltage 5V 6V 8V 8.5V 9V 10V 12V 15V 18V 20V 24V 27V BEIJING ESTEK ELECTRONICS CO.,LTD 2 78XX Electrical characteristics Parameter Output voltage** IO= 5mA to 1A, VI= 7V to 20V, P 15W Input regulation Ripple rejection Output regulation Output resistance Temperature coefficient of output voltage Output noise voltage Dropout voltage Bias current Bias current change Short-circuit output current Peak output current * VI= 7V to 25V VI= 8V to 18V, f= 120Hz IO= 5mA to 1.5A IO= 250mA to 750mA f= 1KHz IO= 5mA f= 10 Hz to 100 KHz IO= 1A 0 C to 12562 C 25 C 0 C to 125 C 0 C to 125 C 25 C 25 C 25 C 0 C to 125 C 25 C 25 C 750 2.2 A 7805 = 500mA (unless otherwise noted) Min 25 4.8 C 0 C to 125 C 4.75 25 C 7805 Typ 5 5 3 1 78 15 5 0.017 -1.1 40 2.0 4.2 100 50 Units Max 5.2 5.25 100 50 mV dB mV V Test Conditions* Electrical characteristics at specified virtual junction temperature, V I= 10V, IO 8 1.3 0.5 mV/ C V V mA VI= 7V to 25V IO= 5mA to 1A Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible.

BEIJING ESTEK ELECTRONICS CO.,LTD 8 78XX Typical Applications Circuit For a positive regulator, a 0.33-|iF bypass capacitor should be used on the input terminals. While not necessary for stability, an output capacitor of O.ljiF may be used to improve the transient response of the regulator. These capaci- tors should be on or as near as possible to the regulator terminals. See Fig.1. 78XX Fig. 1.
