Toshiba introduces Small 300mA LDO Regulator

The TCR3UG series uses WCSP4F packages with dimensions of 0.645x0.645mm and 0.33mm thick, which helps reduce the size of mobile devices, especially in applications such as smart cards. &; The device has an input voltage range of 1.5 to 5.5V DC and typically has a quiescent current of only 340nA. With this ultra-low quiescent current, they still have 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 and in applications that are susceptible to noise or power supply voltage fluctuations. The TCR3UG series has 31 output voltages ranging from 0.8V to 5.0V. In addition, a variety of models are available with and without automatic output discharge, allowing designers to easily select the device that best meets the requirements of the application.
