79L06 D D D D D D Negative-Voltage Regulators 3-Terminal Regulators Output Current Up to 100 mA No External Components Required Internal Thermal-Overload Protection Internal Short-Circuit Current Limiting Direct Replacement for Motorola MC79L06 Series C OUTPUT INPUT COMMON I O TO–92 79L06ACZ description This series of fixed negative-voltage integrated-circuit SOT-89 voltage regulators is designed for a wide range of 79L06CPK COMMON INPUT OUTPUT applications. 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 make them essentially immune to overload. When used as a replacement for a zener-diode and resistor combination, these devices can provide ef fective improvement in output iimpedance of two orders of magnitude, with lower bias current. electrical characteristics at specified virtual junction temperature, VI = 11V, I o = 40mA (unless otherwise noted) 79L06 TJ‡ TEST CONDITIONS PARAMETER MIN 25°C V 7 V tto 20 V I 1 mA A to t 40 mA A Output voltage I o=1 to 70mA, V = -12V to - 20V Input voltage regulation VI = -8.5 to -20V VI = -9V to -20V Ripple rejection VI = -10V to -20V f = 120 Hz IO = 1 mA to 40mA Output voltage regulation Output noise voltage IO = 1 mA to 100mA f = 10 Hz to 100 kHz Dropout voltage Biascurrent Bias ccurrent rrent Bias current change -5.76 MAX -6 Full range -5.7 -6.24 -6.3 Full range -5.7 -6.3 25°C 25°C 25 C 25°C 25°C 25 C 55 175 45 125 49 mV mV mV mV 16 µV 25°C 1.7 25°C 3 Fullll range F Full V dB 9 25°C 125°C VI = -9V to -20V IO = 1 mA to 40 mA UNIT TYP V 6 5.5 1.5 0.1 mA mA mA mA ‡ Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. All characteristics are measured with a 0.33-µF capacitor across the input and a 0.1-µF capacitor across the output.
