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.

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 TDA3682 (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 A (typical value) with the regulator 2 (BU5V) active.
