LDO linear regulator features ultra-fast transient response

Magnachip Semiconductor Corporation has released a new LDO linear regulator highlighting an ultra-fast transient response for a UFS-based MCP.

The company's LDO linear regulator is intended for the power supply of NAND flash in UFS-based MCP with an input voltage of up to 500mA. It decreases input noise with its power supply rejection ratio function while giving a low-leakage current of 75uA in deep sleep mode, which improves battery life and power efficiency.

A key feature of this new product is an ultra-fast transient response, reducing output-voltage fluctuations. Frequent fluctuations in voltage commonly occur in UFS-based MCPs due to varying levels of read and write performance. However, ultra-fast transient response regulates those fluctuations to a steady-state within 100 nanoseconds.

The line regulation and load regulation in UFS-based MCP is sustained at 0.2% and 0.5%, respectively, which will ensure stable power supply. Also, the dropout voltage is as low as 0.3V, which makes the linear regulator excellent for low-power domain operations of batteries.

“The demand for advanced power ICs is growing as electronic devices become more sophisticated and have increasingly stringent requirements for stable and efficient power supply,” said YJ Kim, CEO of Magnachip. “We will continuously expand our Power IC portfolio by delivering premium products for a wide range of data storage applications.”
