The “TCR3UG series” are 300 mA output and small size LDO regulator ICs for power management system built in IoT modules, wearable devices smartphones etc.
The new products, TCR3UG series regulators feature low quiescent bias current and have improved tradeoff between ripple rejection ratio and load transient response in industry's highest level.
The TCR3UG series regulators deliver the industryʼs best trade-offs between these characteristics[1]. They also deliver various protection features, such as thermal shutdown, overcurrent protection and inrush current suppression.
Housed in the industry-leading small WCSP4F package[1], which measures 0.645×0.645 mm (typ.), t=0.33 mm (max), the TCR3UG series helps reduce the size and thickness of mobile applications.
The new LDO regulators are suitable for use in sensor power supply in applications that require long battery life, and applications susceptible to noise and voltage fluctuations. The series offers 62 LDO regulators, available with 31 output voltages, ranging from 0.8 V to 5.0 V, and with and without automatic output discharging, allowing easy selection for the regulator that best suits the customerʼs requirements.
