Toshiba launches 0.8×1.2×0.33mm CMOS LDO regulator

Toshiba has introduced a 1.3A output current CMOS LDO regulator for mobile device power supplies with  a typical dropout voltage of just 92mV (@0.9V, 1.0A) in a 0.8mm x 1.2mm x 0.33mm WCSP6F package.

The 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 suitable 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 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, says Toshiba, making it suitable for mobile and module applications that require small footprints and low profiles.

A  high typical ripple rejection ratio (90dB @0.9V, 1kHz) can help in 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 in the CMOS LDO regulator 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.
