TO-220AB OUTPUT COMMON INPUT description This series of fixed-voltage 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. Each of these regulators can deliver up to 500 mA of output current. The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents and also as the power-pass element in precision regulators. KTP PACKAGE (TOP VIEW) OUTPUT COMMON INPUT The COMMON terminal is in electrical contact with the mounting base. The µA78M00C series is characterized for operation over the virtual junction temperature range of 0°C to 125°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal-overload protection may be activated at power levels slightly above or below the rated dissipation. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero. recommended operating conditions Input voltage, VI MIN MAX µA78M05 7 25 µA78M06 8 25 µA78M08 10.5 25 µA78M09 11.5 26 µA78M10 12.5 28 µA78M12 14.5 30 µA78M15 17.5 30 µA78M20 23 35 µA78M24 27 38 Output current, IO Operating virtual junction temperature, TJ 0 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 UNIT V 500 mA 125 °C 3 µA78M00 SERIES POSITIVE-VOLTAGE REGULATORS SLVS059D – JUNE 1976 – REVISED JULY 1999 electrical characteristics at specified virtual junction temperature, VI = 10 V, IO = 350 mA, TJ = 25°C (unless otherwise noted) TEST CONDITIONS† PARAMETER VI = 7 V to 20 V O tp t voltage Output oltage Input voltage regulation TJ = 0°C to 125°C VI = 7 V to 25 V IO = 200 mA IO = 100 mA, TJ = 0°C to 125°C IO = 300 mA VI = 8 V to 18 V,, f = 120 Hz Output voltage regulation IO = 5 mA to 500 mA IO = 5 mA to 200 mA Output noise voltage TYP 4.8 5 4.75 IO = 5 mA, f = 10 Hz to 100 kHz MAX 5.2 5.25 3 100 1 50 62 62 TJ = 0°C to 125°C 20 100 10 50 40 4.5 Short-circuit output current VI = 35 V VI = 8 V to 25 V, TJ = 0°C to 125°C TJ = 0°C to 125°C mV/°C µV 6 mA V 0.8 0.5 300 Peak output current mV 200 2 Bias current IO = 200 mA, IO = 5 mA to 350 mA V dB 80 –1 Dropout voltage Bias current change UNIT mV VI = 8 V to 20 V VI = 8 V to 25 V Ripple rejection Temperature coefficient of output voltage µA78M05C MIN mA mA 0.7 A † All characteristics are measured with a 0.33-µF capacitor across the input and a 0.1-µF capacitor across the output.
