Despite its small package, the TCR15AG series can drive a high current of 1.5A, suiting it for power supply applications in Wi-Fi chipsets for smartphones and tablets, cameras and wireless modules. The new series can also control power supply in applications requiring a high current, including notebook PCs, digital camcorders, storage devices and set-top boxes.

TCR15AG series deliver the industry’s best-in-class ripple rejection ratio and load transient response. They significantly reduce the ripple noise from a power management IC (PMIC) or a DC-DC converter that is often a limiting factor in the power supply for cameras and radio-frequency (RF) circuits. This helps to minimize output voltage fluctuations that occur in response to sharp changes in current during mode transitions in cameras and RF circuits.

Low voltage dropout is secured by use of an external bias voltage pin (VBIAS), which helps to improve system power efficiency and contributes to longer charge life for the batteries of mobile products.

The series offers two kinds of output voltage—adjustable output between 0.60V and 3.6V via external resistors, and fixed output voltages from 0.65 V to 3.6 V—enabling support for a wide range of power supply applications.

The TCR15AG series extensive protection features include overcurrent protection and thermal shutdown, positioning it as a high-efficiency LDO solution for applications requiring highly regulated voltage in the high-current region and low power consumption.
