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. 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.
TDA3607
All output pins are fully protected. The regulators are protected against load dump (regulators will switch-off at supply voltages higher than 20 V) and short-circuit (foldback current protection). The total timing of a semi on/off logic set is shown in Fig.3.

Application information NOISE Table 1 Noise figures NOISE FIGURE (V)(1) REGULATOR at OUTPUT CAPACITOR (F) 10 1 2 3 Note 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). - - - 47 150 150 200 100 - - -
When a high frequency capacitor of 220 nF in parallel with an electrolytic capacitor of 100 F is connected directly to pins 3 and 8 (supply and ground) the noise is minimal. STABILITY The regulators are made stable with the externally connected output capacitors. The value of the output capacitors can be selected by referring to the graphs illustrated in Figs 6 and 7. When an electrolytic capacitor is used the temperature behaviour of this output capacitor can cause oscillations at cold temperature. The following two examples explain how an output capacitor value is selected.

Multiple voltage regulator with switch
Example 1
Regulator 1 is made stable with an electrolytic output capacitor of 68 F (ESR = 0.5 ), at -30 C the capacitor value is decreased to 22 F and the ESR is increased to 3.5 . The regulator will remain stable at -30 C.
TDA3607
Solution
Use a tantalum capacitor of 10 F 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 F electrolytic capacitor (ESR = 3.3 ), at -30 C the capacitor value is decreased to 3 F and the ESR is increased to 23.1 . The regulator will be unstable at -30 C (see Fig.7).

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. 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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA3607
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). 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. 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 data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
