5V/100mA Low-Drop Fixed-Voltage Regulator (analog TLE4264G, Siemens) 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 low- drop voltage less than 0.5V at load current of 100mA. Applied in power sources of electronic equipment including automotive electronics. The circuit is protected against overload of either positive or negative polarity, internal limiting of maximum load current with temperature reset of output voltage Features:
- 5V output voltage tolerance ± 2%
- Low-drop voltage
- Very low current consumption
- Built-in overtemperature protection
- Protection against pins reverse polarity
- Junction temperature range from - 40 up to +125°С. Pin Definition Pin Symbol Catalogue description Function UI Input voltage Input 2, 4 GND Ground Ground UQ 5-V output voltage Output

The same parameter in analog IC is Rth ja = 125 ОС/Вт (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: Rth ja = Rth jc + Rth ca , (1) Where Rth jc – IC thermal resistance “junction-case”, ОС/Wt. . The same parameter in analog IC is Rth jc = 25 ОС/Wt ((by “Siemens” information data). Thermal resistance “case-air” Rth ca 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 ОС. 2 Absolute maximum power Ptot,Wt, dissipated by the IC at the ambient temperature TA , is determined as: Ptot = (125 - TA) / Rth ja , (2) where 125 – absolute maximum junction operation temperature, ОС
