Output Voltage Adjustment of the LDO03C Series

The ultra-wide output voltage trim range offers major advantages to users who select the
LDO010C series. It is no longer necessary to purchase a variety of modules in order to cover
different output voltages. The output voltage can be trimmed in a range of 0.59-5.1 Vdc.
When the LDO03C converter leaves the factory, the output has been adjusted to the default
voltage of 0.59 V.

Notes:

1 Measured as per recommended system capacitance. See Application Note 186.
2 di/dt = 10 A/µs, Vin = Nom, Tc = 25 °C, load change = 0.50 lo to full lo and full lo

to 0.50.
3 External input fusing is recommended.
4 Additional part numbers may be available with different output voltages.
5 Airflow dependent, 100 LFM minimum required.
6 No capacitors needed for ripple current capability.
7 No capacitors needed for stability.
8 NOTICE: the input voltage must be greater than the programmed output

voltage. the max duty cycle is 95%. These non-isolated dc-dc modules are buck

converters.
