IC of powerful adjustable voltage regulator with low residual voltage lower than 1,5A and reference voltage 1,25 V is purposed for producing constant temperature-stabilized voltage of positive polarity by means of the value set by external resistive di- vider and used in electronic equipment as a source of stabilized supply. Properties:

  • Reference voltage 1,25V
  • Output current up to 7,5 A
  • Input-output voltage difference, UIN - UO up to 30 V
  • Residual voltage lower than 1,5 V
  • Overload protection
  • Embedded temperature protection
  • Operation range of chip temperature from 0 up to +125°Ñ. Table 1 – Description of regulator IC pins in 3-pin package KT-9 Pin No. Description Name

Output voltage Uo, V, is defined by formula: U U R R I RO ref Adj= + +( )1 2 1 2 , Where Uref - reference voltage, V, IAdj - adjustment current, mkA. Since IADJ has values not more than 120 mkA, inaccuracy dependent on this value for Uo – is minor.

connected to the input and ÑÎ=100 mkF – to the output;

2 Reference voltage U ref in adjustable regulator is measured between outputs Output and

Adjust on resistance R1 (figure 1); 3 Parameters stipulated in table 1 are ensured for constant chip temperature T J. Measure- ment of parameters should be performed using heatsink and pulse technique;
