TPS79933QDDCRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS79933QDDCRQ1 is an automotive-qualified, 200-mA low-dropout linear regulator designed for applications requiring excellent AC performance and low power consumption.

 

This LDO regulator features a fixed 3.3V output and a very low quiescent current of 40 µA typical. It boasts a high Power Supply Rejection Ratio (PSRR) of 66 dB at 1 kHz and ultra-low noise of 29.5 µV RMS, making it suitable for noise-sensitive applications. The device has a fast start-up time of 45 µs and a low dropout voltage of 100 mV at 200 mA output.

 

The TPS79933QDDCRQ1 is stable with ceramic capacitors and provides 2% overall accuracy over load, line, and temperature variations. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

Packaged in a thin SOT-23-5 (SOT-23-THN) surface-mount package, this regulator is ideal for space-constrained designs. It operates over an industrial temperature range of -40°C to +125°C.
