Philips Semiconductors Product specification Multiple voltage regulators with switch FUNCTIONAL DESCRIPTION TDA3608Q; TDA3608TH The hold output is only activated when VREG3 > 1.3 V. When pin HOLD is connected via a pull-up resistor to the output of regulator 3 spikes will be minimized to 1.3 V (maximum value) because the hold output is only disabled when VREG3 < 1.3 V.

Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. SOLDERING Introduction This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011).
Philips Semiconductors Product specification Multiple voltage regulators with switch During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. MANUAL SOLDERING Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead.
