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. 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. electrical characteristics at specified virtual junction temperature, VI = otherwise noted) PARAMETER TEST CONDITIONS TJ‡ UNITJ MIN TYP MAX I 1 mA to 40 mA 25°C Output voltage V 7 V t I 1 A t 40 A Full range V IO = 1 mA to 70 mA Full range Input VI = 25°C mVvoltage regulationVI = 25°C mV Ripple rejection VI = f = 120 Hz 25°C dB Output IO = 1 mA to 100 mA 25°C mVvoltage regulationIO = 1 mA to 40 mA 25°C mV Output noise voltage f = 10 Hz to 100 kHz 25°C mV Dropout voltage 25°C V Bias current 25°C mABias c rrent 125°C mA Bias VI = Full range 1.5 mAcurrent change IO = 1 mA to 40 mA F ll range 0.1 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-mF capacitor across the input and a 0.1-mF capacitor across the output. Full range for the 78L05 is TJ = 0°C to 70°C Wing Shing Computer Components Co., (H.K.)Ltd. Tel:(852)2341 9276 Fax:(852)2797 8153 Homepage: http://www.wingshing.com E-mail: wsccltd@hkstar.com
