The LDO03C is a new high density,
open frame, non-isolated converter
for space sensitive applications. This
model has a wide input range of 3-13.8
V and offers a 0.59-5.1 V adjustable
output with 3 A capability. Typical
efficiency for this model is 90% (5 Vin,
2.5 Vout, 3 A load). The 5-pin version of
this voltage device offers the additional
features of enable, and with a default
wide adjustable ouput voltage range or
option of power good.
