TPS79330YZQR

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

The TPS79330YZQR is a fixed-output linear low-dropout regulator manufactured by Texas Instruments. It provides a fixed 3V output with a maximum continuous current of 200mA. The device operates from an input voltage range up to 5.5V and features a typical dropout voltage of 0.2V at full load. Quiescent current is specified at 220µA. Power supply rejection ratio (PSRR) ranges from 70dB at 100Hz to 43dB at 100kHz. It includes protection against overcurrent, thermal overload, reverse polarity, and under-voltage lockout. The component is housed in a 5-DSBGA package and supports operation between -40°C and 125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized channels as the TPS79330YZQR has reached end-of-life status. Confirm that replacement parts like the TPS79930 series meet all electrical specifications for your design. Check datasheet revisions for any parameter changes in successor models before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3V output is required with moderate current demands. Consider the 5-DSBGA package constraints for PCB layout. Evaluate thermal performance given the 220µA quiescent current and 0.2V dropout at 200mA. Ensure input voltage does not exceed 5.5V maximum rating during normal operation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the TPS793xx family of ultralow-noise, high-PSRR LDO regulators designed for sensitive analog and RF applications. The TPS79330 variant specifically offers a fixed 3V output. It shares architectural similarities with other members but differs in output voltage configuration and specific protection thresholds defined by the manufacturer's design parameters.
