Features

  • Output voltage 5 V or 10 V  Output voltage tolerance ≤ ±2%  120 mA current capability  Very low current consumption  Low-drop voltage  Overtemperature protection  Reverse polarity proof  Wide temperature range  Suitable for use in automotive electronics I n h i b i t  Green Product (RoHS compliant)  AEC Qualified Functional Description TLE 4266 is a low-drop voltage regulator for 5 V or 10 V supply in a PG-SOT223-4 SMD package. The IC regulates an input voltage VI in the range of 5.5 V/10.5 V < VI < 45 V to VQ,nom = 5 V/10 V. The maximum output current is more than 120 mA. The IC can be switched off via the inhibit input, which caus es the current consum ption to drop below 10 µA. The IC is shortcircuit-proof and incorporates a temperature protection which turns off the IC at overtemperature. Choosing 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 line inductivity and input capacitance can be clamped. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values CQ ≥ 10 µF and an ESR ≤ 10 Ω within the whole operating temperature range.

Data Sheet 3 Rev. 2.5, 2008-03-10 Circuit Description The device includes a precise reference voltage, which is very accurate due to resistor adjustment. A control amplifie r compares the divided output voltage to this reference voltage and drives the base of the PNP series transistor through a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The IC also incorporates a number of protection circuitry for:  Overload  Overtemperature  Reverse polarity Figure 2 Block Diagram Reference BandgapAdjustment Sensor Temperature Saturation Control and Protection Circuit Control Amplifier Buffer INH GND AEB01725 Ι
