Functional Description
The TLE4276isalow-drop voltage regulator in aTO package. T he IC regulates an input
voltageupto40Vto
V
(V). The maximum output current is 400 mA. The IC can be switched off via the inhibit
input, which causes the currentconsumption todropbelow 10
proof and includes temperature protection which turns off the device at overtemperature.

The controlamplifier compares areference voltage toa voltage that is proportional to the
output voltage and drives the base of the series transistor via a buffer. Saturation control
as a function of the load current prevents any oversaturation of the power element. The
IC also incorporates a number of internal circuits for protection against:
• Overload
• Overtemperature
• Reverse polarity

Application Information for Variable Output Regulator TLE 4276 V, SV, DV, GV
The output voltage of the TLE 4276 V can be adjusted between 2.5 V and 20 V by an
external output voltage divider, closing the control loop to the voltage adjust pin VA.
The voltage at pin VA is compared to the internal reference of typical 2.5 V in an error
amplifier. It controls the output voltage.
