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. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal-shutdown features of these regulators make them essentially immune to overload. When used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtained, together with lower bias current. The µA78L00C 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 MIN µA78L02AC µA78L05C, µA78L05AC µA78L06C, µA78L06AC Input voltage VI voltage, µA78L08C, µA78L08AC µA78L09C, µA78L09AC µA78L10AC µA78L12C, µA78L12AC µA78L15C, µA78L15AC Output current, IO Operating virtual junction temperature, TJ 0 4.75 7 8.5 10.5 11.5 12.5 14.5 17.5 MAX 20 20 20 23 24 25 27 30 100 125 mA °C V UNIT POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3 µA78L00 SERIES POSITIVE-VOLTAGE REGULATORS SLVS010I – JANUARY 1976 – REVISED JULY 1999 electrical characteristics at specified virtual junction temperature, VI = 9 V, IO = 40 mA (unless otherwise noted) PARAMETER TEST CONDITIONS TJ† 25°C Output voltage VI = 4.75 V to 20 V, 4 75 V IO = 1 mA to 70 mA VI = 4.75 V to 20 V VI = 5 V to 20 V VI = 6 V to 20 V, IO = 1 mA to 100 mA IO = 1 mA to 40 mA f = 10 Hz to 100 kHz f = 120 Hz IO = 1 mA to 40 mA 0°C to 125°C 0°C to 125°C 25°C 25°C 25°C 25°C 25°C 25°C 125°C VI = 5 V to 20 V IO = 1 mA to 40 mA 0°C to 125°C 43 µA78L02C MIN 2.5 2.45 2.45 20 16 51 12 6 30 1.7 3.6 6 5.5 2.5 0.1 50 25 TYP 2.6 MAX 2.7 2.75 2.75 100 75 mV dB mV µV V mA mA V UNIT Input voltage regulation Ripple rejection Output voltage regulation Output noise voltage Dropout voltage Bias current Bias current change † Pulse-testing techniques maintain TJ as close to TA as possible.
