TPS7B6850QPWPRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS7B6850QPWPRQ1 is an automotive-qualified, 500-mA, low-dropout (LDO) voltage regulator designed for high-voltage applications. It offers a wide input voltage range from 4V to 40V, withstanding transients up to 45V.

 

This LDO regulator provides a stable 5V fixed output voltage with a maximum output current of 500 mA. Key electrical features include a high Power Supply Rejection Ratio (PSRR) of 55 dB at 100 KHz, a low quiescent current of 19 µA typical at light loads, and a maximum dropout voltage of 600 mV at 500 mA.

 

Designed for reliability, the TPS7B6850QPWPRQ1 includes protection features such as over-current and over-temperature protection. It also incorporates a configurable watchdog timer, an enable pin, and a power good output, making it suitable for safety-critical automotive systems. The device operates within an ambient temperature range of -40°C to 125°C.

 

The regulator is supplied in a 28-pin HTSSOP package, suitable for surface mounting. It is stable with a wide range of output capacitance and ESR values, simplifying design.
