TPS7A3401DGNR Description

Short technical summary and product information.

The Texas Instruments TPS7A3301DGNR is a high-performance, low-noise, negative adjustable low-dropout (LDO) voltage regulator. It is designed to provide a stable and clean negative voltage supply for sensitive electronic circuits.

 

Key electrical specifications include an input voltage range of -3V to -20V and a maximum output current of 200mA. The output voltage is adjustable, typically ranging from -1.18V to -18V, with an accuracy of 2.5%. It features a low quiescent current of 50µA and exhibits excellent noise performance with only 80µV RMS of noise from 10Hz to 100kHz. The device also boasts a Power Supply Rejection Ratio (PSRR) of 50dB at 1kHz and greater than 27dB across a wide frequency range up to 1MHz.

 

For reliable operation, the TPS7A3301DGNR includes built-in protection features such as over-current and over-temperature shutdown. It is stable with ceramic capacitors as small as 2.2µF, simplifying external component selection. The regulator is available in an 8-pin HVSSOP package, suitable for surface mounting.

 

This LDO regulator is well-suited for applications requiring a clean, stable negative voltage rail, such as in battery-powered devices, portable electronics, and various analog signal processing circuits where noise sensitivity is a concern.
