Ripple and noise reduced to max in LDO from Toshiba

Toshiba has announced it will launch a 200mA output single LDO regulator fabricated with a newly developed micro-CMOS process. Its features include low-noise output, high ripple rejection ratio, excellent responsiveness under high-speed loads and low drop-out.

The new LDO regulator achieves a low-noise output of 18µVrms (2.5V output), an excellent ripple rejection ratio of 62dB at high frequency (2.5V output, f = 10kHz), excellent responsiveness under high-speed loads of ?VOUT = ±65mV (IOUT = 1mA ? 150mA, COUT = 1.0µF), and low drop-out characteristics of 80mV (2.5V output, IOUT = 100mA).

Integration into an ultra-small WCSP4 package (0.79mm x 0.79mm x 0.5mm) ensures suitability for applications demanding high-density packaging, such as mobile devices.

Samples are available now and mass production is scheduled to start in January.

Applications: Mobile phones, tablet PCs, portable audio players, digital cameras, digital video cameras and other small mobile devices
