UA78L06AC 5.95 6.2 6.45
TJ = 0°C to 125°C UA78L06C 5.6 6.8
UA78L06AC 5.9 6.5
TJ = 0°C to 125°C, and IO = 1 mA to 70 mA UA78L06C 5.6 6.8
UA78L06AC 5.9 6.5

UA78L06AC 40 48
Output voltage regulation TJ = 25°C IO = 1 mA to 100 mA 16 80 mV
IO = 1 mA to 40 mA 9 40
Output noise voltage TJ = 25°C, and f = 10 Hz to 100 kHz 46 µV
Dropout voltage TJ = 25°C 1.7 V
Bias current TJ = 25°C 3.9 6 mA
TJ = 125°C 5.5
Bias current change TJ = 0°C to 125°C VI = 9 V to 20 V 1.5 mA
IO = 1 mA to 40 mA UA78L06C 0.2
UA78L06AC 0.1
(1) Applies to UA78L06C and UA78L06AC.
(2) Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. For legacy chip, temperature range for the UA78L06C and UA78L06AC is TJ = 0°C to 125°C.
