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. at specified virtual junction temperature, V I = 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, Output voltage V VI = 14.5 V to 27 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 Ripple rejection VI = 15 V to 25 V, f = 120 Hz 0 °C to 125°C 55 71 dB 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 Bias current 25 °C 4.3 8 mA VI = 14.5 V to 30 V 1 Bias current change 0 °C to 125°C mA IO = 5 mA to 1 A 0.5 Short-circuit output current 25 °C 350 mA Peak output current 25 °C 2.2 A (1) Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible.
