5 / 20 page www.ti.com Electrical Characteristics Electrical Characteristics µA78M00 SERIES POSITIVE-VOLTAGE REGULATORS SLVS059P – JUNE 1976 – REVISED OCTOBER 2005 at specified virtual junction temperature, V I = 8 V, IO = 350 mA, TJ = 25°C (unless otherwise noted) µA78M33C PARAMETER TEST CONDITIONS(1) UNIT MIN TYP MAX 3.2 3.3 3.4 IO = 5 mA to 350 mA, Output voltage(2) V VI = 8 V to 20 V TJ = 0°C to 125°C 3.1 3.3 3.5 VI = 5.3 V to 25 V 9 100 Input voltage regulation IO = 200 mA mV VI = 8 V to 25 V 3 50 IO = 100 mA, TJ = 0°C to 125°C 62 VI = 8 V to 18 V, Ripple rejection dB f = 120 Hz IO = 300 mA 62 80 Output voltage regulation VI = 8 V, IO = 5 mA to 500 mA 20 100 mV Temperature coefficient IO = 5 mA, TJ = 0°C to 125°C –1 mV/ °C of output voltage Output noise voltage f = 10 Hz to 100 kHz 40 200 µV Dropout voltage 2 V Bias current 4.5 6 mA IO = 200 mA, VI = 8 V to 25 V, TJ = 0°C to 125°C 0.8 Bias current change mA IO = 5 mA to 350 mA, TJ = 0°C to 125°C 0.5 Short-circuit output current VI = 35 V 300 mA Peak output current 700 mA (1) All characteristics are measured with a 0.33- µF capacitor across the input and a 0.1-µF capacitor across the output. Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. (2) This specification applies only for dc power dissipation permitted by absolute maximum ratings at specified virtual junction temperature, V I = 10 V, IO = 350 mA, TJ = 25°C (unless otherwise noted) µA78M05C PARAMETER TEST CONDITIONS(1) UNIT MIN TYP MAX 4.8 5 5.2 IO = 5 mA to 350 mA, Output voltage V VI = 7 V to 20 V TJ = 0°C to 125°C 4.75 5.25 VI = 7 V to 25 V 3 100 Input voltage regulation IO = 200 mA mV VI = 8 V to 25 V 1 50 IO = 100 mA, TJ = 0°C to 125°C 62 VI = 8 V to 18 V, Ripple rejection dB f = 120 Hz IO = 300 mA 62 80 IO = 5 mA to 500 mA 20 100 Output voltage regulation mV IO = 5 mA to 200 mA 10 50 Temperature coefficient IO = 5 mA, TJ = 0°C to 125°C –1 mV/ °C of output voltage Output noise voltage f = 10 Hz to 100 kHz 40 200 µV Dropout voltage 2 V Bias current 4.5 6 mA IO = 200 mA, VI = 8 V to 25 V, TJ = 0°C to 125°C 0.8 Bias current change mA IO = 5 mA to 350 mA, TJ = 0°C to 125°C 0.5 Short-circuit output current VI = 35 V 300 mA Peak output current 0.7 A (1) All characteristics are measured with a 0.33- µF capacitor across the input and a 0.1-µF capacitor across the output.
