3 A current rating

Input voltage range 3-13.8 V Adjustable output voltage 0.59-5.1 V

• Optional 3-pin model factory set
• Optional 5-pin model factory set with power good option Excellent transient response Power enable (5-pin model) Minimum airflow Small package Termination voltage capacity RoHS Compliant 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. [ 2 Y E A R W A R R A N T Y ] TÜV
