Functional Description
The TLE 4276-2 is a low-drop voltage regulator in a TO package. The IC regulates an
input voltage up to 40 V to
output current is 400 mA. The IC can be switched off via the inhibit input, which causes
the current consumption to drop below 10 µA. The IC is short-circuit-proof and includes
temperature protection which turns off the device at overtemperature.

operating temperature range.
Circuit Description
The control amplifier compares a reference voltage to a 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:
