Functional Description

The TLE 4476 is a monolithic integrated voltage regulator providing two output voltages,

Q1 is a 3.3 V output for loads up to 350 mA and Q2 is a 5 V output providing 430 mA.

The device is available in the PG-TO252-5-11 (D-Pak) package. Output 2 can be

switched ON/OFF via the Enable input EN.

The TLE 4476 is designed to supply microprocessor systems under the severe

conditions of automotive applications and is therefore equipped with additional

protection functions against overload, short circuit and overtemperature.

Application Circuit

Input, Output

The input capacitor C_Iis necessary for compensating line influences. Using a resistor of

approx. 1 Ω in series with C_I, the LC circuit of input inductivity and input capacitance can

be damped. To stabilize the regulation circuits of the stand-by and main regulator, output

capacitors C_Q1and C_Q2are necessary. Stability is guaranteed at values C_Q1≥ 10 μF

(ESR ≤ 2 Ω) and C_Q2≥ 10 μF (ESR ≤ 3 Ω) within the operating temperature range.

Enable

Using the enable feature the output 2 (5 V output) can be switched ON or OFF. The

enable input can be connected directly to terminal 30 (battery line) or 15 (ignition line). It

is also possible to control the output 2 via the microcontroller.
