The regulators are protected against load dump (regulators will switch-off at supply voltages higher than 20 V) and short-circuit (foldback current protection). FUNCTIONAL DESCRIPTION The TDA3607 is a multiple output voltage regulator with three independent switchable regulators. When the supply voltage (VP > 4.5 V) is available, regulators 1, 2 and 3 can be operated by means of 3 independent enable inputs. The total timing of a semi on/off logic set is shown in Fig.3. Schmitt-trigger functions are included to switch-off the regulators at low battery voltage (VP < 4 V). A hysteresis is included to avoid random switching. handbook, full pagewidth load dump 18.0 V VP 9.4 V 4.5 V 4.0 V ≥2.2 V enable regulator 1 ≤2.0 V 9.0 V regulator 1 0V ≥2.2 V enable regulator 2 ≤2.0 V 5.0 V regulator 2 0V ≥2.2 V enable regulator 3 ≤2.0 V 5.0 V regulator 3 0V MBG720 Fig.3 Timing diagrams. 1997 May 05 4 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch TDA3607 LIMITING VALUES SYMBOL PARAMETER CONDITIONS MIN.

Minimum operating voltage, only if VP has exceeded 4.5 V. 2. The quiescent current is measured in the standby mode. So, the enable inputs of regulator 1, 2 and 3 are LOW (Ven < 1 V). 3. The drop-out voltage of regulators 1, 2 and 3 is measured between VP and VREGn. 4. At current limit, IREGmn is held constant (see Fig.4 for behaviour of IREGmn). 5. The foldback current protection limits the dissipated power at short-circuit (see Fig.4). 6. Perform the load regulation test with sine wave load of 10 kHz on the regulator output under test. Measure the RMS ripple voltage on each of the remaining regulator outputs, using a 80 kHz low-pass filter. 1997 May 05 7 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch handbook, halfpage TDA3607 MGB755 9V handbook, halfpage VREG1 VREG2 MGB756 5.0 V 2V 1V ≥300 mA IREGsc1 IREGm1 IREGsc2 ≥50 mA a.

Note The following two examples explain how an output capacitor value is selected. 1. Measured at a bandwidth of 200 kHz. The noise on the supply line depends on the value of the supply capacitor and is caused by a current noise (output noise of the regulators is translated into a current noise by means of the output capacitors). 1997 May 05 9 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch TDA3607 Example 1 Solution Regulator 1 is made stable with an electrolytic output capacitor of 68 µF (ESR = 0.5 Ω), at −30 °C the capacitor value is decreased to 22 µF and the ESR is increased to 3.5 Ω. The regulator will remain stable at −30 °C. Use a tantalum capacitor of 10 µF or a large electrolytic capacitor. The use tantalum capacitors is recommended to avoid problems with stability at cold temperatures. Example 2 Regulator 2 is made stable with a 10 µF electrolytic capacitor (ESR = 3.3 Ω), at −30 °C the capacitor value is decreased to 3 µF and the ESR is increased to 23.1 Ω.

If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “IC Package Databook” (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
