Multiple voltage regulator with

power switches

TDA3682

FEATURES

General

• Good stability for any regulator with almost any output

capacitor

• Five voltage regulators (BU5V, illumination, AM, FM

and audio)

• Mode selection by three enable control pins

• Low dropout voltage output stages (PNP output stage)

• High ripple rejection

• Low noise for all regulators

• Two power switches (power antenna and power control

function).

Protections

• Reverse polarity safe (down to −18 V without high

reverse current)

• Able to withstand voltages up to 18 V at the output

(supply line may be short-circuited)

• ESD protection of all pins

• Thermal protection to avoid thermal break down

• Load dump protection

• Regulator outputs are DC short-circuited safe to ground

and supply voltage

• Foldback current limit protection for all regulators

• Loss of ground protection for power switches.

GENERAL DESCRIPTION

The TDA3682 is a multiple output voltage regulator with

power switches, intended for use in car radios with or

without a microprocessor.

The TDA3682 contains the following:

• Four switchable regulators and one permanent active

regulator (BU5V)

• Two power switches with loss of ground protection

• Three enable control inputs for selecting the regulators

(illumination, audio, AM or FM) and the power switches

(PANT and PCON); the standby mode is selected with

all enable control inputs at LOW level.

The quiescent current has a very low level of 120

µA

(typical value) with the regulator 2 (BU5V) active.
