1.3A LDO Regulator with 92mV Dropout Voltage

Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced the launch of a 1.3A output current CMOS LDO regulator, the TCR13AGADJ, for use in the power supplies of mobile devices, housed in the WCSP6F package. The TCR13AGADJ measures just 0.8mm x 1.2mm, with a maximum thickness of 0.33mm. Shipments start from today.

TCR13AGADJ is an LDO regulator that can be used in a variety of applications including Wi-Fi chipsets for smartphones and tablets, power supplies for cameras and RF modules, and power supply control of wearable devices, notebook PCs, digital video cameras, storage devices and set-top boxes. By utilizing an external bias power supply terminal (VBAT), the new product claims the industry’s leading-class low dropout voltage, making it possible to improve the efficiency of the power supplies of the sets that it is used in.

In addition, the new product claims the industry’s leading-class high ripple rejection ratio, which can help in drastically reducing ripple noise from dc-dc converters and power management ICs, common problems users face when trying to supply power to camera and RF parts. Using an external resistor, the output voltage of the new product can be adjusted within the wide range of 0.55V to 3.6V to meet the needs of the power supply application in which it is used.

Built-in protection features include over-current protection, over-temperature protection, inrush current protection and auto-discharge function. These features support creation of high efficiency LDO solutions for applications that need stable output voltage at high output currents, and low power consumption.
