MC2840T12-1 Datasheet
The input voltage range of the PTH04070W is from 3 V t0 5.5 V, allowing operation from either a 3.3-V or 5-V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH04070W can step down to voltages as low as 0.9 V from a 5-V input bus, with typically less than l W of power dissipation. The output voltage can be adjusted to any voltage over the range, 0.9 V t0 3.6 V, using a single external resistor. Operating features include an undervoltage lockout (UVLO), on/off inhibit, output overcurrent protection, and overtemperature protection. Target applications include telecommunications, test and measurement applications, and high-end consumer products. The modules are available in both through-hole and surface-mount package options, including tape and reel.

* In order to measure at Ta -Tj (pulse measurement), fluctuations in output resulting from temperature fluctuations are not included * Design guaranteed. (Not all products have been inspected.) A capacitor (O.OlyF) is used between pin 4 and pin 5, to improve ripple rejection. ~Not designed for radiation resistance.
