TPS7A2018PDBVR Description

Short technical summary and product information.

The Texas Instruments TPS7A2018PDBVR is an ultra-small LDO linear regulator capable of sourcing 300mA of output current. It is engineered for applications demanding low noise and high Power Supply Rejection Ratio (PSRR), making it suitable for RF and other sensitive analog circuits. This device offers an ultra-low noise performance without the need for an external noise bypass capacitor.

 

Key electrical specifications include an input voltage range of 1.6V to 6.0V and a fixed output voltage of 1.8V with a tolerance of ±1.5%. It features a very low dropout voltage of 140mV at 300mA and a low quiescent current of 6.5µA, ideal for battery-powered applications. The regulator provides a high PSRR of 95dB at 1kHz and features protection against over current, over temperature, and under voltage lockout.

 

The TPS7A2018PDBVR is available in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package. It is stable with a minimum of 1µF ceramic output capacitor, allowing for a small overall solution size. The device also includes a smart enable input circuit with an internal pulldown resistor, simplifying external component requirements.
