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.

Features
◆ Up to 150mA per regulator output
◆ Low quiescent current
◆ Low dropout voltage
◆ Stable operation with ceramic caps
◆ Very low 50µVRMS output noise
◆ Wide selection of output voltages
◆ Tight load and line regulation
◆ Current and thermal limiting
◆ Reverse input polarity protection
◆ <1.5uA off-mode current
◆ Logic controlled enable

Applications
◆ Cellular telephones
◆ Palmtop/Laptop computers
◆ Battery-powered equipment
◆ Bar code scanners
◆ SMPS post regulator/dc to dc modules
◆ High efficiency linear power supplies
