LDO regulator IC targets IoT applications

January 22, 2018 // By Julien Happich
Toshiba Electronics Europe's TCR3UG series of small package, low-dropout (LDO) regulators offers an output current of 300mA for IoT modules, wearable devices and smartphones. Housed in a WCSP4F package, only 0.645x0.645mm and 0.33mm thin, the TCR3UG series helps to reduce the size and especially the thickness of mobile devices which is essential in some applications such as smart cards.

The devices have an input voltage range of 1.5 to 5.5V DC and exhibit a quiescent current of typically just 340nA. With this ultra-low quiescent current, they still offer an excellent ripple rejection ratio of 70dB and a load transient response of ±60mV.

The new LDO regulators are suitable for use as part of the power supply in applications that require long battery life, as well as applications that are susceptible to noise or fluctuations of the supply voltage. The TCR3UG-series is available with 31 output voltages, ranging from 0.8V to 5.0V. Additionally, variants with and without automatic output discharge are available, allowing designers to easily select the device that best meets the application's requirements.
