Overview
The TPS73501DRBR from Texas Instruments is a 500-mA, low-dropout (LDO) linear voltage regulator designed for high-performance applications. This regulator is part of the TPS735 series and is known for its low quiescent current, ultra-low noise, and high power-supply rejection ratio (PSRR). It is available in an 8-pin VSON package, making it suitable for space-constrained designs. The device operates over a wide input voltage range of 2.7 V to 6.5 V and can provide adjustable output voltages from 1.25 V to 6 V. It is fully specified from -40°C to 125°C, ensuring reliability across various environmental conditions.
