TPS72518DCQR Description

Short technical summary and product information.

The Texas Instruments TPS72518DCQR is a 1A low-dropout (LDO) linear regulator with a fixed 1.8V output voltage. It is designed for powering DSPs, FPGAs, and microcontrollers. The device operates over an input voltage range of 1.8V to 6V and features a low dropout voltage of 170mV at 1A.

 

Key electrical characteristics include a typical ground current of 210µA at full load and less than 1µA standby current. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The regulator also includes an integrated supervisor with a 50ms reset delay time and offers 60dB PSRR at 1kHz.

 

This LDO is suitable for applications requiring stable power delivery and is available in a 5-lead SOT-223-6 surface mount package. Its design allows for stable operation with any type or value of output capacitor, providing flexibility in transient performance tailoring.
