Package

P-SOT223-4-4 (SMD)

Functional Description

TLE 4264 is a 5-V low-drop fixed-voltage regulator in an SOT-223 package. The IC

regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQrated = 5.0 V. The

maximum output current is more than 120 mA. This IC is shortcircuit-proof and features

temperature protection that disables the circuit at overtemperature.

Dimensioning Information on 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 inductivity and input capacitance can

be damped. 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 operating

temperature range.
