LDO regulator targets wearable, mobile devices

LDO regulator targets wearable, mobile devices

The TCR13AGADJ offers a typical dropout voltage of just 92mV (@0.9V, 1.0A) and is supplied in a WCSP6F package that the company believes in the smallest in the industry.

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 aimed at 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 regulator achieves a low typical dropout voltage of 92mV (@ 0.9V, 1.0A.

The WCSP6F package is the industry’s leading small package for 1.3A LDO regulators, making it suitable for mobile and module applications that require small footprints and low profiles. A high typical ripple rejection ratio of 90dB @0.9V, 1kHz can help to reduce 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.
