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.
