TLE 4264 G is a 5-V low-drop fixed-voltage regulator in an SOT-223 package. The IC
regulates an input voltage
V
I
in the range 5.5 V <

= 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.
