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

I in the range of 5.5 V/10.5 V < VI < 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

I is 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

Q is 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.
