TLE 4266 G
Functional Description
TLE 4266 G is a 5 V low-drop voltage regulator in a P-SOT223-4-2 SMD package. The
IC regulates an input voltage
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 A. The IC is shortcircuit-
proof and incorporates temperature protection that disables the IC an overtemperature.
