These include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these regulators can deliver up to 100 mA of output current. The internal current-limiting and thermal-shutdown features essentially make the regulators immune to overload. When used as a replacement for a zener-diode and resistor combination, these devices can provide an effective improvement in output impedance of two orders of magnitude, with lower bias current. OUTPUT INPUT COMMON The MC79L00C series is characterized for operation over the virtual junction temperature range of 0C to 125C.

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), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) - TA)/JA. Operating at the absolute maximum TJ of 150C can impact reliability. 2. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions 2 VI Input voltage IO TJ Output current Operating virtual junction temperature MIN MAX MC79L05 -7 -20 MC79L12 -14.5 -27 MC79L15 -17.5 -30 0 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 UNIT V 100 mA 125 C MC79L00 SERIES NEGATIVE-VOLTAGE REGULATORS SLVS011C - OCTOBER 1982 - REVISED APRIL 2001 electrical characteristics at specified virtual junction temperature, VI = -10 V, IO = 40 mA (unless otherwise noted) PARAMETER Output voltage Input regulation Ripple rejection TEST CONDITIONS VI = -7 V to -20 V, IO = 1 mA to 40 mA VI = -10 V, IO = 1 mA to 70 mA VI = -7 V to -20 V VI = -8 V to -20 V VI = -8 V to -18 V, f = 120 Hz TJ MC79L05C TYP MAX MIN TYP MAX 25C -4.6 -5 -5.4 -4.8 -5 -5.2 0C to 125C -4.5 -5.5 -4.75 -5.25 0C to 125C -4.5 -5.5 -4.75 -5.25 25C 25C 40 Output regulation 25C Output noise voltage f = 10 Hz to 100 kHz 25C 40 Dropout voltage IO = 40 mA 25C 1.7 Bias current change VI = -8 V to -20 V IO = 1 mA to 40 mA 200 150 150 100 49 IO = 1 mA to 100 mA IO = 1 mA to 40 mA Bias current MC79L05AC MIN 41 49 V mV dB 60 60 30 30 mV V 40 1.7 V 25C 6 6 125C 5.5 5.5 1.5 1.5 0.2 0.1 0C to 125C UNIT mA mA All characteristics are measured with a 0.33-F capacitor across the input and a 0.1-F capacitor across the output.
