The Texas Instruments TPS79433DCQ is a positive fixed output linear voltage regulator designed for efficient power management. This component delivers a stable 3.3V output with a maximum output current of 250mA, featuring a low dropout voltage of 0.2V at its rated current. Its quiescent current is 220 µA, contributing to power efficiency in battery-operated devices. The TPS79433DCQ incorporates robust protection features including over current, over temperature, reverse polarity, and under voltage lockout (UVLO). With a Power Supply Rejection Ratio (PSRR) ranging from 65dB to 40dB across the 100Hz to 100kHz frequency range, it offers excellent noise immunity. The device operates within an ambient temperature range of -40°C to 125°C and is supplied in a SOT-223-6 surface-mount package. Its enable control feature allows for power sequencing and management. This regulator is suitable for applications in consumer electronics, industrial automation, and communication systems.
