Ultra-small Package and Low-noise 200mA LDO Regulator for Mobile Devices: TCR2DG Series

200mA output single LDO regulator featuring low-noise output, high ripple rejection ratio, excellent responsiveness under high-speed loads and low drop-out, and that uses a newly developed micro CMOS process.
This product achieves a low-noise output of 18μVrms (2.5V output), excellent ripple rejection ratio 62dB at a high frequency (2.5V output, f = 10kHz), excellent responsibility under high-speed loads of ΔVOUT = ±65mV (IOUT = 1mA ⇔ 150mA, COUT = 1.0μF), and low drop-out characteristics of 80mV (2.5V output, IOUT = 100mA).
By using an ultra-small (0.79mm × 0.79mm × 0.5mm) WCSP4 package, this LDO regulator is suitable for applications requiring high-density packaging, such as mobile devices.
