Low Drop Voltage Regulator

Features

• Output voltage 5 V, 8.5 V or 10 V

• Output voltage tolerance ≤ ±4%

• Current capability 400 mA

• Low-drop voltage

• Very low current consumption

• Short-circuit proof

• Reverse polarity proof

• Suitable for use in automotive electronics

• Green Product (RoHS compliant) version of TLE 4274

Functional Description

The TLE 4274 is a low drop voltage regulator available in
a TO220, TO252 and TO263 package. The IC regulates
an input voltage up to 40

V to V
(V85) and 10 V (V10). The maximum output current is
400 mA. The IC is short-circuit proof and incorporates
temperature protection that disables the IC at
overtemperature. A 3.3 V and 2.5 V version is also
available. For information about the low output voltage
types please refer to the data sheet TLE

Dimensioning Information on External Components

The input capacitor CI is necessary for compensating line influences. Using a resistor of
approx. 1 Ω 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.

C

Stability is guaranteed at values
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 includes a number of internal circuits for protection against:

• Overload

• Overtemperature

• Reverse polarity

≥ 22 μF and an ESR of ≤ 3 Ω within the operating
