Functional Description
The TLE 4276 is a low-drop voltage regulator in a TO package. The IC regulates an input
voltage up to 40 V to
V
Q,nom
= 5.0 V (V50), 8.5 V (V85), 10 V (V10) and adjustable voltage
(V). The maximum output current is 400 mA. The IC can be switched off via the inhibit
input, which causes the current consumption to drop below 10
←
A. The IC is short-circuit-
proof and includes temperature protection which turns off the device at overtemperature.
Dimensioning Information on External Components
The input capacitor
C
I
is necessary for compensation of line influences. Using a resistor
of approx. 1
τ
in series with
C
I
, the oscillating of input inductivity and input capacitance
can be damped. The output capacitor
C
Q
is necessary for the stability of the regulation
circuit. Stability is guaranteed at values
C
Q
∫

F and an ESR of
3
τ
within the
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:
Overload
Overtemperature
Reverse polarity
