TPS71728DCKR Description

Short technical summary and product information.

The Texas Instruments TPS71728DCKR is a low-dropout (LDO) linear voltage regulator designed for efficient power management. It provides a stable 2.8V output voltage with a maximum current capability of 150 mA.

 

Key electrical features include a very low dropout voltage of 170 mV typical at 150 mA, ensuring efficient operation even with low input voltages. The regulator boasts ultra-high Power Supply Rejection Ratio (PSRR) of 70 dB at 1 kHz, 67 dB at 100 kHz, and 45 dB at 1 MHz, making it suitable for noise-sensitive applications. It also exhibits low noise performance with 30 µV RMS typical (100 Hz to 100 kHz).

 

This device operates over a temperature range of -40°C to 125°C and is housed in a compact 5-pin SC-70 package, suitable for surface mount applications. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS71728DCKR is ideal for various applications requiring a reliable and low-noise voltage supply, such as portable electronics, battery-powered devices, and noise-sensitive analog circuits.
