FUNCTIONAL DESCRIPTION
The TDA3682 is a multiple output voltage regulator with
power switches, intended for use in car radios with or
without a microprocessor.
It contains:
• Four switchable regulators and one permanent active
regulator
• Two power switches with loss of ground protection
• Three enable control inputs EN1, EN2 and EN3.
The quiescent current has a very low level of 120 µA
(typical value) with the regulator 2 (BU5V) active.
Because of low voltage operation of the application, low
dropout voltage regulators are used in the TDA3682.
Output selection
Regulator 2 is always active and can not be controlled.
All the other regulators and both power switches can be
controlled by using pins EN1, EN2 and EN3:
• Pin EN1 controls regulator 1 (illumination); see Table 1
• Pin EN2 selects regulator 3, 4 or 5 (audio, AM or FM);
see Table 2
• Pin EN3 selects power switches 1 or 2 (PANT or
PCON); see Table 3.
Pins EN2 and EN3 are three-state level control inputs:
• L means: VEN ≤ 1 V
• M means: 2 V ≤ VEN ≤ 3 V
• H means: VEN ≥ 4 V.
