TLE 4276
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 VQ,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.
www.DataSheeDt4Uim.comensioning Information on External Components
The input capacitor CI is necessary for compensation of line influences. Using a resistor
of approx. 1 τ in series with CI, the oscillating of input inductivity and input capacitance
can be damped. The output capacitor CQ is necessary for the stability of the regulation
circuit. Stability is guaranteed at values CQ 22 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
