4 / 14 page www.ti.com Electrical Characteristics Electrical Characteristics TL780 SERIES POSITIVE-VOLTAGE REGULATORS SLVS055M – APRIL 1981 – REVISED OCTOBER 2006 at specified virtual junction temperature, V I = 19 V, IO = 500 mA (unless otherwise noted) TL780-12C PARAMETER TEST CONDITIONS TJ(1) UNIT MIN TYP MAX 25 °C 11.88 12 12.12 IO = 5 mA to 1 A, P ≤ 15 W, Output voltage V VI = 14.5 V to 27 V 0 °C to 125°C 11.76 12.24 VI = 14.5 V to 30 V 1.2 12 Input voltage regulation 25 °C mV VI = 16 V to 22 V 1.2 12 Ripple rejection VI = 15 V to 25 V, f = 120 Hz 0 °C to 125°C 65 80 dB IO = 5 mA to 1.5 A 6.5 60 Output voltage regulation 25 °C mV IO = 250 mA to 750 mA 2.5 36 Output resistance f = 1 kHz 0 °C to 125°C 0.0035 Ω Temperature coefficient of IO = 5 mA 0 °C to 125°C 0.6 mV/ °C output voltage Output noise voltage f = 10 Hz to 100 kHz 25 °C 180 µV Dropout voltage IO = 1 A 25 °C 2 V Input bias current 25 °C 5.5 8 mA VI = 14.5 V to 30 V 0.4 1.3 Input bias-current change 0 °C to 125°C mA IO = 5 mA to 1 A 0.03 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. Thermal effects must be taken into account separately. All characteristics are measured with a 0.33- µF capacitor across the input and a 0.22-µF capacitor across the output. at specified virtual junction temperature, V I = 23 V, IO = 500 mA (unless otherwise noted) TL780-15C PARAMETER TEST CONDITIONS TJ(1) UNIT MIN TYP MAX 25 °C 14.85 15 15.15 IO = 5 mA to 1 A, P ≤ 15 W, Output voltage V VI = 17.5 V to 30 V 0 °C to 125°C 14.7 15.3 VI = 17.5 V to 30 V 1.5 15 Input voltage regulation 25 °C mV VI = 20 V to 26 V 1.5 15 Ripple rejection VI = 18.5 V to 28.5 V, f = 120 Hz 0 °C to 125°C 60 75 dB IO = 5 mA to 1.5 A 7 75 Output voltage regulation 25 °C mV IO = 250 mA to 750 mA 2.5 45 Output resistance f = 1 kHz 0 °C to 125°C 0.0035 Ω Temperature coefficient of IO = 5 mA 0 °C to 125°C 0.62 mV/ °C output voltage Output noise voltage f = 10 Hz to 100 kHz 25 °C 225 µV Dropout voltage IO = 1 A 25 °C 2 V Input bias current 25 °C 5.5 8 mA VI = 17.5 V to 30 V 0.4 1.3 Input bias-current change 0 °C to 125°C mA IO = 5 mA to 1 A 0.02 0.5 Short-circuit output current 25 °C 230 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.
