TPS78318DDCT Description

Short technical summary and product information.

The TPS78318DDCT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for battery-powered applications requiring ultralow quiescent current. This device provides a stable 1.8V output with a maximum output current of 150mA.

 

Key electrical specifications include an input voltage range of 2.2V to 5.5V and a typical quiescent current of only 500nA. The regulator offers a typical dropout voltage of 130mV at 150mA and maintains 3% accuracy over load, line, and temperature variations. It also features a PSRR of 13dB at 100KHz and noise of 86 µVrms.

 

Protection features include overcurrent, over temperature, and reverse polarity protection. The device is enabled via a CMOS logic-level compatible pin. It is supplied in a compact SOT-23-5 Thin package, suitable for surface mounting.

 

This LDO is ideal for portable electronics, battery-powered devices, and other applications where low power consumption and small size are critical.
