TPS79318YZQR Description

Short technical summary and product information.

The Texas Instruments TPS79318YZQR is a 200-mA low-dropout linear regulator with an ultralow noise and high power-supply rejection ratio (PSRR). It provides a fixed 1.8V output voltage and is suitable for noise-sensitive analog components in portable RF electronics.

 

Key electrical characteristics include an input voltage range of 2.7V to 5.5V, a maximum output current of 200mA, and a typical quiescent current of 0.17mA. The regulator exhibits a low noise level of 32 μVRMS and a high PSRR of 70 dB at 10 kHz. It also features a fast start-up time of 50 μs and a very low dropout voltage of 112 mV at 200mA.

 

The TPS79318YZQR is designed to be stable with a small 2.2-μF ceramic capacitor on the output. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The device operates over a temperature range of -40°C to 125°C.

 

This regulator is available in a compact 5-DSBGA (5-UFBGA) surface-mount package, making it ideal for space-constrained applications like Bluetooth devices and wireless LAN systems.
