TPS7A2033PDBVR

The TPS7A2033PDBVR from Texas Instruments is an ultra-small, low-dropout (LDO) linear regulator capable of sourcing 300mA of output current. It is engineered to deliver low noise and high Power Supply Rejection Ratio (PSRR), making it suitable for sensitive analog circuits. This regulator achieves ultra-low noise performance without requiring an external noise bypass capacitor.

Key electrical characteristics include a wide input voltage range of 1.6V to 6.0V and an output voltage range of 0.8V to 5.5V. It offers a typical quiescent current of 6.5µA, ideal for battery-powered devices. The device boasts a typical PSRR of 95dB at 1kHz and a low output voltage noise of 7µVRMS.

Designed for ease of use, the TPS7A2033PDBVR features a very low dropout voltage, specified at a maximum of 140mV at 300mA for a 3.3V output. It is stable with a minimum of 1µF ceramic output capacitor. The regulator operates within a temperature range of -40°C to 125°C and is available in a SOT-23-5 package, suitable for surface mounting.

This LDO regulator is well-suited for applications requiring clean power delivery, such as RF circuits, sensitive analog systems, and portable electronics where low power consumption is critical.
