TPS79228DBVT Description

Short technical summary and product information.

The Texas Instruments TPS79228DBVT is a high-performance, low-dropout (LDO) linear voltage regulator. It provides a stable 2.8V output voltage with a maximum output current of 100mA. This device is characterized by its low output noise of 27µVrms and a high power-supply rejection ratio (PSRR) of up to 70dB at 100Hz, making it suitable for sensitive analog circuits.

 

The TPS79228DBVT operates from an input voltage range of 2.7V to 5.5V and features a low dropout voltage of typically 55mV at 100mA. It includes an enable pin for power sequencing and control. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount case, this regulator is designed for applications where space is limited. Its thermal resistance is rated at 178°C/W (junction-to-ambient). The device is stable with a minimum load capacitance of 1µF.

 

Key electrical specifications include a quiescent current of 0.2mA (typical) and an accuracy of 2%. The operating temperature range is -40°C to 85°C.
