TPS74601PQWDRBRQ1 Description

Short technical summary and product information.

The TPS74601PQWDRBRQ1 from Texas Instruments is an automotive-qualified linear voltage regulator designed for reliable power management. It operates with an input voltage range of 1.5V to 6.0V and provides an adjustable output voltage from 0.55V to 5.5V, capable of delivering up to 1A of current.

 

Key electrical specifications include a low quiescent current of 25µA typical, a high Power Supply Rejection Ratio (PSRR) of up to 53dB at 100kHz, and an accuracy of ±1.5% maximum. The device features an ultra-low dropout voltage of 265mV maximum at 1A (for 3.3VOUT), ensuring efficient operation even under heavy loads. Protection features include overcurrent, overtemperature, and undervoltage lockout (UVLO).

 

This LDO regulator is available in small wettable flank packages, including 8-SON (3x3mm) and 8-VDFN (2x2mm) options, facilitating easier assembly and inspection. It is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to 125°C (TA). The regulator also includes a power-good output option for monitoring output voltage status.
