6.12 Electrical Characteristics: UA78L10 (Legacy Chip Only)

at specified junction temperature, VI = 14 V, CIN = 0.33 µF, COUT = 0.1µF and IO = 40 mA (unless otherwise noted)(1)
PARAMETER TEST CONDITIONS(2) MIN TYP MAX UNIT
Output voltage VI = 13 V to 25 V, and IO = 1 mA to 40 mA TJ = 25°C 9.6 10 10.4 V
TJ = 0°C to 125°C 9.5 10.5
TJ = 0°C to 125°C, and IO = 1 mA to 70 mA 9.5 10.5
Input voltage regulation TJ = 25°C VI = 13 V to 25 V 51 175 mV
VI = 14 V to 25 V 42 125
Ripple rejection TJ = 25°C, VI = 15 V to 25 V, and f = 120 Hz 37 44 dB
Output voltage regulation TJ = 25°C IO = 1 mA to 100 mA 20 90 mV
IO = 1 mA to 40 mA 11 40
Output noise voltage TJ = 25°C, and f = 10 Hz to 100 kHz 62 µV
Dropout voltage TJ = 25°C 1.7 V
Bias current TJ = 25°C 4.2 6 mA
TJ = 125°C 5.5
Bias current change TJ = 0°C to 125°C VI = 14 V to 25 V 1.5 mA
IO = 1 mA to 40 mA 0.1
(1) Applies to UA78L10AC.
(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 UA78L10AC is TJ = 0°C to 125°C.
