Description

The NCV1124DG is a low dropout positive voltage regulator that belongs to the Sensor and Detector Interfaces category. It is capable of providing an output current of over 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. This model has eight fixed output voltages (1.5 V, 1.8 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V) with no minimum load requirement to maintain regulation. It also has an adjustable output version that can be programmed from 1.25 V to 18.8 V using external resistors. The reference/output voltage is trimmed to ±1.0% accuracy.
