TPS7A2028PYCJR

TPS7A2028PYCJR Description

The TPS7A2028PYCJR is a high-performance, low-noise, low-quiescent current linear regulator designed by Texas Instruments. This device is part of the Power Management Integrated Circuit (PMIC) category and is ideal for applications requiring a fixed output voltage of 2.8V with a maximum input voltage of 6V. It can deliver up to 300mA of output current while maintaining an ultra-low dropout voltage of 0.14V at full load. The regulator is designed with a positive output configuration and features a quiescent current of only 15 µA, making it suitable for low-power applications. The TPS7A2028PYCJR also includes essential control features such as current limit, enable, and soft start, along with comprehensive protection features like over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO). The device is available in a surface-mount package and is shipped in tape and reel format.
