Features

• Output voltage tolerance ≤ ±2%  Low-drop voltage  Very low current consumption  Overtemperature protection  Short-circuit proof  Suitable for use in automotive electronics  Reverse polarity  Green Product (RoHS compliant)  AEC Qualified Functional Description TLE 4264 is a 5-V low-drop fixed-voltage regulator in an PG-SOT223-4 package. The IC regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQrated = 5.0 V. The maximum output current is more than 120 mA. This IC is shortcircuit-proof and features temperature protection that disables the circuit at overtemperature. Dimensioning Information on External Components The input capacitor Ci is necessary for compensating line influences. Using a resistor of approx. 1 Ω in series with Ci, the oscillating of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaran teed at values CQ ≥ 10 µF and an ESR ≤ 10 Ω within the operating temperature range.

Data Sheet 2 Rev. 2.3, 2008-03-07 TLE 4264 Figure 1 Pin Configuration (top view) Circuit Description The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control, working as a function of load current, prevents any over-saturation of the power element. The IC is protected against overload, overtemperature and reverse polarity.
