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

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

µA.

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

is necessary for compensation of line influences. Using a resistor

of approx. 1

Ω

in series with

, the oscillating of input inductivity and input capacitance

can be damped. The output capacitor

is necessary for the stability of the regulation

circuit. Stability is guaranteed at values

≥

µF

and an ESR of

≤

Ω

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
