300mA LDO regulator for the IoT combines low quiescent bias current with high ripple rejection
The TCR3UG series regulators trade off of ripple rejection ratio at 70dB and a load transient response of 60mV to provide a quiescent bias current of 0.34 μA which Toshiba says in the industry’s lowest for this class of regulator.
They also include various protection features, such as thermal shutdown, overcurrent protection and inrush current suppression. Housed in the chip scale WCSP4F package which measures 0.645mm x 0.645mm (typ.) with a maximum thickness of 0.33mm, 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 voltage points, ranging from 0.8V to 5.0V, and with and without automatic output discharging.
