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.

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.
