TPS7B7702QPWPRQ1 +BOM

Automotive 300-mA, off-battery (40-V), dual-channel adjustable antenna low-dropout voltage regulator

TPS7B7702QPWPRQ1 Information

Description

The TPS7B7702QPWPRQ1 is a low-dropout linear regulator (LDO) from Texas Instruments (TI). It's designed for automotive and industrial applications, offering a wide input voltage range of 4.5V to 40V and adjustable output voltage between 1.5V and 20V. The device features current sense and adjustable current-limit capabilities, making it suitable for power management in consumer electronics and battery-powered devices. The TPS7B7702QPWPRQ1 is AEC-Q100 qualified with a temperature range of -40°C to 125°C, making it suitable for automotive applications. It also features integrated protection and diagnostics, including thermal shutdown, undervoltage lockout, short-circuit protection, and reverse battery polarity protection. This LDO regulator offers high accuracy current-sense detection, high power-supply rejection ratio, and a dropout voltage of 500mV at 100mA load. Its compact HTSSOP-16 package makes it suitable for space-constrained applications.
