TPS7A3001DRBR Description

Short technical summary and product information.

The Texas Instruments TPS7A3001DRBR is a versatile negative adjustable low-dropout (LDO) voltage regulator designed for applications requiring low noise and high power-supply ripple rejection (PSRR). It can deliver up to 200mA of output current with an adjustable output voltage ranging from -1.18V to -33V, drawing input from -3V to -35V.

Key electrical characteristics include a typical quiescent current of 50 µA and low noise performance of 14 µVrms (20 Hz to 20 kHz). The PSRR is rated at 72 dB at 120 Hz, ensuring clean power delivery. Protection features such as over-current and over-temperature shutdown are integrated for reliability.

This regulator is available in an 8-SON (3x3) package and is designed for surface mounting. It requires a minimum load capacitance of 2.2 µF for stability and includes a CMOS logic-level-compatible enable pin and a soft-start feature to manage inrush current.

The TPS7A3001DRBR is suitable for various power management applications where stable, low-noise negative voltage is critical.
