TPS7A4201DGNR

The Texas Instruments TPS7A4201DGNR is a linear, low-dropout (LDO) voltage regulator designed for efficient power management. It features a wide input voltage range from 7 V to 28 V and can supply a maximum output current of 50 mA. The adjustable output voltage can be set from 1.2 V to 26 V, providing flexibility for different system requirements.

Key electrical characteristics include a typical quiescent current of 25 µA, which is crucial for low-power applications, and a low quiescent current of 4.1 µA during shutdown. The regulator offers a typical dropout voltage of 290 mV at 50 mA and provides protection features such as over current, over temperature, and under voltage lockout (UVLO).

This device is supplied in an 8-pin HVSSOP package, with dimensions of 3 mm x 4.9 mm and an exposed pad for enhanced thermal performance. The mounting type is surface mount, making it suitable for compact PCB designs. The operating temperature range is -40°C to 125°C, ensuring reliable operation in demanding environments.

The TPS7A4201DGNR is stable with ceramic capacitors, requiring a minimum input capacitance of 1 µF and a minimum output capacitance of 4.7 µF. It includes a CMOS logic-level-compatible enable pin for control.
