Toshiba introduces Small 300mA LDO Regulator
Post Date: 2018-01-25
Toshiba introduced the first product in the TCR3UG family of small package LDO regulators with an output current of 300mA for power management of IoT modules, wearable devices and smartphones.
The TCR3UG family, housed in the WCSP4F package, measures 0.645x0.645mm and 0.33mm thick, helping to reduce the size of mobile devices, especially in applications such as smart cards.
The part's input voltage range is 1.5 to 5.5V DC and quiescent current is typically only 340nA. With this ultra-low quiescent current, they still have a good 70dB ripple rejection ratio and ± 60mV load transient response.
The new LDO regulators are ideal for power supplies in applications that require long battery life, as well as applications that are susceptible to noise or supply voltage fluctuations. The TCR3UG family has 31 output voltages ranging from 0.8V to 5.0V. In addition, variations are available with and without automatic output discharge, allowing designers to easily select the device that best meets the application's requirements.
