SC632AULTRT

The SC632A is a high-current voltage regulator using Semtech’s proprietary low-noise charge pump technology. The charge pump provides a low EMI solution compared to inductive boost regulators. 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 5.0V. Unlike an LDO, drop-out is avoided when the input is less than 5.0V. Instead, a charge pump is activated to provide voltage boost and the head-room needed for voltage regulation.

• Input voltage range — 2.95V to 5.5V
• Vout tolerance — 5.0V ±3%
• Continuous output current — 275mA
• Peak output current — 400mA
• Three charge pump modes — 1x, 1.5x and 2x
• Output ripple voltage — 50mVPP , typical
• Short circuit, over-voltage, and over-temperature protection
• Soft-start functionality
• Shutdown current — 0.1µA, typical
• Ultra thin package — 2 x 2 x 0.6 (mm)
• Lead-free and halogen-free
• WEEE and RoHS compliant
