5-V Low Drop Fixed Voltage Regulator
Features
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
maximum output current is more than 120 mA. This IC is shortcircuit-proof and features
temperature protection that disables the circuit at overtemperature.
