TPS74518PQWDRVRQ1 LDO voltage regulator IC Positive Fixed 1 Output 500mA
The TPS74518PQWDRVRQ1 is a 500-mA, ultra-low-dropout (LDO) voltage regulator designed by Texas Instruments (TI) for automotive and industrial applications requiring high precision and reliability. It operates within a -40°C to +125°C temperature range (junction temperature up to 150°C) and supports an input voltage range of 1.5V to 6.0V, making it suitable for battery-powered systems. The chip is available in a compact 6-pin, 2mm × 2mm WSON package with wettable flanks for automated optical inspection (AOI). It features a fixed 1.8V output with ±0.85% accuracy (±1.5% max over temperature) and integrates a power-good (PG) indicator for monitoring output voltage status. The LDO’s ultra-low dropout voltage (160mV max at 500mA) and low quiescent current (25µA typical) ensure high efficiency in energy-sensitive applications.
