TPS78318DDCR Description

Short technical summary and product information.

The TPS78318DDCR from Texas Instruments is a linear, low-dropout (LDO) voltage regulator designed for battery-powered applications requiring ultralow quiescent current. This device offers a fixed 1.8V output voltage and can supply up to 150mA of current.

 

Key electrical specifications include an input voltage range of 2.2V to 5.5V and a typical quiescent current of only 500nA. The regulator features a low dropout voltage of 130mV at 150mA and maintains 3% accuracy over load, line, and temperature variations. It also includes enable control, thermal shutdown, and overcurrent protection features.

 

The TPS78318DDCR is housed in a compact SOT-23-5 Thin package, suitable for surface mounting. Its operating temperature range is -40°C to 105°C, making it suitable for various environmental conditions. The regulator is stable with a minimum load capacitance of 1µF.

 

This LDO is ideal for power management in portable electronics, wearables, and other low-power devices where efficiency and space are critical considerations.
