TPS78218DDCR Description

Short technical summary and product information.

The Texas Instruments TPS78218DDCR is a high-performance, low-dropout (LDO) linear voltage regulator designed for various power management applications. It provides a stable 1.8V fixed output voltage with a maximum output current of 150mA.

 

Key electrical specifications include an input voltage range of 2.2V to 5.5V and an ultra-low quiescent current of typically 500nA, making it suitable for battery-powered devices. The regulator offers a low 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 an enable pin for power sequencing.

 

Protection features include overcurrent, overtemperature, and reverse polarity protection, enhancing system reliability. The TPS78218DDCR is available in a compact SOT-23-5 Thin package, suitable for surface mount applications where space is constrained. Its operating temperature range is -40°C to 125°C.
