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. (2) This parameter is validated by design and verified during product characterization. It is not tested in production. uA7812 Electrical Characteristics at specified virtual junction temperature, VI = 19 V, IO = 500 mA (unless otherwise noted) μA7812C PARAMETER TEST CONDITIONS TJ (1) UNIT MIN TYP MAX 25°C 11.5 12 12.5 IO = 5 mA to 1 A, VI = 14.5 V to 27 V, Output voltage V PD ≤ 15 W 0°C to 125°C 11.4 12.6 VI = 14.5 V to 30 V 10 240 Input voltage regulation 25°C mV VI = 16 V to 22 V 3 120 VI = 15 V to 25 V, f = 120 Hz 55 71 Ripple rejection(2) 0°C to 125°C dB VI = 15 V to 25 V, f = 120 Hz (KCT) 61 IO = 5 mA to 1.5 A 12 240 Output voltage regulation 25°C mV IO = 250 mA to 750 mA 4 120 Output resistance f = 1 kHz 0°C to 125°C 0.018 Ω Temperature coefficient of output voltage IO = 5 mA 0°C to 125°C –1 mV/°C Output noise voltage f = 10 Hz to 100 kHz 25°C 75 μV Dropout voltage IO = 1 A 25°C 2 V (1) Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible.
