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.
