PARAMETER SYMBOL RATINGS UNIT Input Voltage VIN 35 V Output Current I OUT 0.5 A Power Dissipation P D Internally Limited W Junction Temperature T J 0 ~ +125 °C Storage Temperature T STG -65 ~ +150 °C Notes:1. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The device could be damaged beyond Absolute maximum ratings. 2. The maximum steady state usable output current are dependent on input voltage, heat sinking, lead length of the package and copper pattern of PCB. The data are showed as electrical characteristics table represents pulse test conditions with junction temperatures specified at the initiation of test.  ELECTRICAL CHARACTERISTICS (TJ=25°C,CI =0.33uF,CO =0.1uF,PD≦7W, unless otherwise specified) For 78T05 (VIN=10V, IOUT=0.5A) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT IOUT=5mA~0.5A 100 mVLoad Regulation VOUT IOUT=5mA~200 mA 50 mV VIN =7V~25V 100 mVLine Regulation VOUT VIN =7.5~20V, IOUT=0.5A 50 mV Quiescent Current I Q I OUT=0.5A 8 mA VUT =7.5~20V 1 mAQuiescent Current Change IQ IOUT=5mA~0.5A 0.5 mA Output Noise Voltage e N 10Hz ≦≦f 100kHz 40 μV Temperature coefficient of VOUT VOUT/TI OUT=5mA -0.6 mV/℃ Ripple Rejection RR V IN =8~18V, f=120Hz 62 80 dB Peak Output Current I PEAK 1.2 A Short-Circuit Current I SC V IN=35V 250 mA Dropout Voltage V D 2 V For 78T06 (VIN=11V, IOUT=0.5A) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT IOUT=5mA~0.5A 60 mVLoad Regulation VOUT IOUT=5mA~200mA 30 mV VIN=8~25V 60 mVLine Regulation VOUT VIN=8.5~21V, IOUT=0.5A 60 mV Quiescent Current I Q I OUT=0.5A 8 mA VIN =8.5~21V 1 mAQuiescent Current Change IQ IOUT=5mA~0.5A 0.5 mA Output Noise Voltage e N 10Hz ≦≦f 100kHz 45 μV Temperature coefficient of VOUT VOUT/TI OUT=5mA -0.7 mV/℃ Ripple Rejection RR V IN =9~19V, f=120Hz 59 75 dB Peak Output Current I PEAK 1.2 A Short-Circuit Current I SC V IN=35V 250 mA Dropout Voltage V D 2 V
