POWER MANAGEMENT Features
Description
The SC633 is a high-current voltage
regulator using Semtech’s proprietary low-noise charge pump technology.
Performance is optimized for use in single Li-Ion battery cell applications.
The
regulator provides the performance of a linear, low drop-out (LDO) voltage
regulator when the input is greater than 5.
3V.
Unlike an LDO, dropout is avoided when the input is less than 5.
3V.
Instead, a charge pump is activated to provide voltage boost and the head-room needed for voltage regulation.
Only two 2.
2µF bucket capacitors are required to deliver the full output current.
The charge pump prov...
