Toshiba Electronics Europe has announced the industry’s smallest 1.3A output current CMOS LDO regulator for mobile device power supplies. The TCR13AGADJ offers a typical dropout voltage of just 92mV (@0.9V, 1.0A) and is supplied in a WCSP6F package measuring just 0.8mm x 1.2mm x 0.33mm (max).
Toshiba’s new regulator can be used in a variety of applications including Wi-Fi® chipsets for smartphones and tablets and power supplies for cameras and RF modules. It is also ideal for power supply control designs in wearable devices, notebook PCs, digital video cameras, storage products and set-top boxes. By using an external bias power supply terminal (VBAT), the new product achieves a leading-class low typical dropout voltage of 92mV (@ 0.9V, 1.0A).
The WCSP6F package is the industry’s leading-class small package for 1.3A LDO regulators, making it suitable for mobile and module applications that require small footprints and low profiles. A leading-class high typical ripple rejection ratio (90dB @0.9V, 1kHz) can help in drastically reducing ripple noise from DC-DC converters and PMIC. These are 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 over a wide 0.55V to 3.6V range. Integrated security features include over-current protection, over-temperature protection, built-in inrush current control and an auto-discharge function. These features support the creation of high efficiency power supply solutions for applications that need a combination of stable output voltage at high output currents and low power consumption.
