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.

Circuit Description
The device includes a precise reference voltage, which is very accurate due to resistor
adjustment. 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. The IC also incorporates a number of protection circuitry for:
