TPS71745DSER Description

Short technical summary and product information.

The TPS71745DSER from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for high-performance applications. It provides a stable 4.5V output voltage with a maximum output current of 150 mA. This regulator boasts an ultra-high Power Supply Rejection Ratio (PSRR) of up to 70 dB at 1 kHz and excellent transient response, making it suitable for noise-sensitive circuits.

 

Key electrical characteristics include a low quiescent current of 80 µA and a low dropout voltage of 170 mV typical at 150 mA. The device operates over an input voltage range of 2.5V to 6.5V and features an enable pin for power sequencing. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS71745DSER is supplied in a compact 6-WSON package with dimensions of 1.5mm x 1.5mm, suitable for space-constrained designs. It is designed for surface mount applications and operates across a wide temperature range of -40°C to 125°C. The regulator is stable with a 1-µF ceramic output capacitor.
