Description
The SC1454 contains two ultra low dropout voltage regulators (ULDOs). It operates from an input voltage range of 2.25V to 6.5V, and a wide variety of output voltage options are available. One ULDO has a fixed output, and the other is either fixed (SETA pin grounded) or adjustable using external resistors. Each ULDO has an independent enable pin.
