5 V/10 V Low Drop Voltage Regulator TLE 4266 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 Inhibit Green Product (RoHS compliant) AEC Qualified SOT223 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 causes the current consumption 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.

A control amplifier 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.
