Features

• Output voltage 5 V ± 2%

• Very low current consumption

• Power-on and undervoltage reset

• Reset low down to VQ = 1 V

• Very low-drop voltage

• Short-circuit-proof

• Reverse polarity proof

• Suitable for use in automotive electronics

• ESD protection > 4 kV

Functional Description

The TLE 4275 is a monolithic integrated low-drop

voltage regulator in a 5-pin TO-package. An input

vo ltage up to 45 V is regulated to VQ,nom = 5.0 V or 3.3V.

The IC is able to driv e loads up to 450 mA a nd is s hort-

circuit proof. At overtemperature the TLE 4275 is turned

off by the incorporated temperature protection. A reset

signal is generated for an output voltage VQ,rt of typ.

4.65 V. The delay time can be programmed by the

external delay capacitor.

*The market versions are PRODUCT PROPOSALS

Dimensioning Information on External Components

The input capacitor CI is necessary for compensation of line influences. Using a resistor

of approx. 1 Ω in series with CI, the oscillating of input inductivity and input capacitance

can be dampe d. The output ca pacitor CQ is neces sary for the sta bility of the reg ulation

circuit. Stability is guaranteed at values CQ ≥ 22 µF and an ESR of ≤ 5 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
