5-V Low Drop Fixed Voltage Regulator

TLE 4264

SOT223

Functional Description

TLE 4264 is a 5-V low-drop fixed-voltage regulator in an PG-SOT223-4 package. The IC
regulates an input voltage VI in the range V < VI < 45 V to VQrated = 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 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 within the operating
temperature range.
