These include on-card regulation for 79L18CPK COMMON INPUT OUTPUT 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 impedance of two orders of magnitude, with lower bias current. electrical characteristics at specified virtual junction temperature, VI = -26V, IO =40mA otherwise noted) PARAMETER TEST CONDITIONS TJ‡ MIN to 20 V V 7Vt I 1 mA A to t 40 mA A I o=1mA to 40mA,VI =-20.5 to -33V IO = 1 mA to 70 mA VI = -20.5 to -33V VI = -21V to -33V VI = -23V to -33V f = 120 Hz IO = 1 mA to 100 mA IO = 1 mA to 40 mA f = 10 Hz to 100 kHz 25°C Full range Full range 25 °C 25 °C C 25 25°C C 25°C 25 25°C 25°C 25°C 12...
