Adjustable and Fixed Voltage Regulator
◈ Descriptions
The SJ1117 series of positive adjustable and fixed regulators are designed to provide 1A with high efficiency.
All internal circuitry is designed to operate down to 1.1V input to output differential.
The SJ1117 offers current limiting and thermal shutdown and over voltage protection.
◈ Features
• Adjustable or fixed output(1.2V, 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5V)
• Output current of 1A
• Safe Operating Area(SOA) Protection
• Over Voltage Protection (OVP)
• Over Current Protection (OCP)
• Thermal shutdown protection
• Low dropout, 1.1V Typical at 1A output current
• Operating temperature range : -40℃ ~ +125℃
• Halogen-Free Package is Available
• High Level ESD Protection : 400V(MM), 4KV(HBM)
