Magnachip has brought out a Low-dropout (LDO) linear regulator with a fast transient response for a UFS-based Multi-Chip Package (MCP).
UFS-based MCP is a memory module that integrates UFS controller and memory ICs, such as DRAM or NAND flash. It is mainly used for the storage function in smartphones.
Magnachip’s LDO linear regulator is designed for the power supply of NAND flash in UFS-based MCP with an input voltage of up to 500mA.
A key feature of this new product is fast transient response, minimizing output-voltage fluctuations.
Frequent changes in voltage normally occur in UFS-based MCPs due to varying levels of read and write performance. However, ultra-fast transient response regulates these fluctuations to a steady state within 100 nanoseconds.
The line regulation and load regulation in UFS-based MCP is maintained at 0.2% and 0.5% respectively, which will guarantee stable power supply. In addition, the dropout voltage is as low as 0.3V, which makes the linear regulator perfect for low-power domain operations of batteries.
This linear regulator also ensures robust circuit protection, such as overcurrent protection, thermal shutdown and the power good signal, which indicates that all of the output voltages are within specification.
