Toshiba Expands Line-up of CMOS-LDO Regulator ICs for Mobile Devices

Toshiba Corporation (TOKYO:6502) has expanded its line-up of CMOS-LDO regulator ICs for mobile devices with the 300mA single output "TCR3DF Series", which delivers low drop-out, low output noise and high-speed load transient response characteristics. Samples will be available in April with mass production scheduled to start in May.

The new line-up covers a range of voltage-clamp type output voltages, from 1.0V to 4.5V, in a SMV (SOT-25: 2.9 x 2.8 x 1.1 mm) package. With additional features of inrush current limit, over-current protection, and over-temperature protection, the devices offer the high performance characteristics required in analog circuits

The new CMOS-LDO regulators are suited for use in a wide range of mobile devices, such as smartphones, mobile phones, tablets, notebook PCs, digital cameras and digital video cameras.
