Notes: 1 * - Rthja - thermal resistance "junction-air" (for IC without additional external heat sink),/Wt. The same parameter in analog IC is Rthja = 125 / (by "Siemens" information data). Thermal resistance "junction-air" of this circuit is determined in the course of research & development work. For the circuit with additional external heat sink:
Rthja = Rthjc + Rthca , (1)
Where Rthjc IC thermal resistance "junction-case", /Wt. . The same parameter in analog IC is Rthjc = 25 /Wt ((by "Siemens" information data). Thermal resistance "case-air" Rthca in the designed IC is determined by heat sink structure and specified by IC consumer. Heat sink, switching "on" mode (power consumed) and ambient temperature should ensure junction temperature not more than TJ +125 .
2 Absolute maximum power Ptot,Wt, dissipated by the IC at the ambient temperature TA , is determined as:
Ptot = (125 - TA) / Rthja , (2) where 125 absolute maximum junction operation temperature,

Description

ILE4264G (analog TLE4264G, Siemens) is a single-chip 5V/100mA low-drop fixed-voltage regulator implemented in a plastic P-SOT223-4-1 package as per Siemens specification.

The circuit of 5V/100mA low-drop fixed-voltage regulator regulates fixed voltage of 5V with lowdrop voltage less than 0.5V at load current of 100mA. Applied in power sources of electronic equipment including automotive electronics. The circuit of the ILE4264 is protected against overload of either positive or negative polarity, internal limiting of maximum load current with temperature reset of output voltage.
