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 V_Iin the range of 5.5 V/10.5 V < V_I< 45 V to

V_Q,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 C_Iis necessary for compensating line influences. Using a resistor of

approx. 1 Ω in series with C_I, the oscillating of input line inductivity and input capacitance

can be clamped. The output capacitor C_Qis necessary for the stability of the regulating

circuit. Stability is guaranteed at values C_Q≥ 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:

• Overload

• Overtemperature

• Reverse polarity
