TPS79330QDBVRQ1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS79330QDBVRQ1 is a fixed-output, positive low-dropout linear regulator designed for automotive applications. It provides a nominal output voltage of 3.0 V with a maximum load current capability of 200 mA. The device operates within an input voltage range of 2.7 V to 5.5 V and maintains regulation with a typical dropout voltage of 200 mV at full load. It features a quiescent current of approximately 220 µA and includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, reverse polarity protection, and undervoltage lockout. The component is qualified to AEC-Q100 standards and functions reliably across an extended junction temperature range of -40°C to 125°C.
