Package
P-SOT223-4-2
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
V
i
in the range of 5.5 V <
V
i
< 45 V to
V
Qrated
= 5 V. The
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
碌A(chǔ).
The IC is shortcircuit-
proof and incorporates temperature protection that disables the IC an overtemperature.
Dimensioning Information on External Components
The input capacitor

is necessary for the stability of the regulating
circuit. Stability is guaranteed at values
