4 / 4 page µA79M00 SERIES NEGATIVE-VOLTAGE REGULATORS SLVS060J – JUNE 1976 – REVISED MAY 2003 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 electrical characteristics at specified virtual junction temperature, VI = –19 V, IO = 350 mA, TJ = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS† µA79M08C UNIT PARAMETER TEST CONDITIONS† MIN TYP MAX UNIT Output voltage VI = 10 5Vto 25 V IO =5mAto350 mA –7.7 –8 –8.3 V Output voltage VI = –10.5 V to –25 V, IO = 5 mA to 350 mA TJ = 0°C to 125°C –7.6 –8.4 V Input voltage regulation VI = –10.5 V to –25 V 8 80 mV Input voltage regulation VI = –11 V to –21 V 4 50 mV Ripple rejection VI = –11.5 V to –21.5 V, IO = 100 mA, TJ = 0°C to 125°C 50 dB Ripple rejection I , f = 120 Hz IO = 300 mA 54 59 dB Output voltage regulation IO = 5 mA to 500 mA 90 160 mV Output voltage regulation IO = 5 mA to 350 mA 60 mV Temperature coefficient of output voltage IO = 5 mA, TJ = 0°C to 125°C –0.6 mV/ °C Output noise voltage f = 10 Hz to 100 kHz 200 µV Dropout voltage IO = 5 mA 1.1 V Bias current 1 2 mA Bias current change VI = –10.5 V to –25 V, TJ = 0°C to 125°C 0.4 mA Bias current change IO = 5 mA to 350 mA, TJ = 0°C to 125°C 0.4 mA Short-circuit output current VI = –30 V 140 mA Peak output current 0.65 A † 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 2- µF capacitor across the input and a 1-µF capacitor across the output. |
