500-mA, low-IQ, low-dropout voltage regulator with enable

TPS73512DRBR General Description

The TPS73512DRBR is a high-performance voltage regulator that offers unparalleled reliability and efficiency. With a dropout voltage of just 280mV, this regulator minimizes power loss and ensures optimal performance in any situation. Its over current, over temperature, reverse polarity, and under voltage lockout protection features provide an additional layer of security, making it a smart choice for mission-critical applications. Designed to handle currents of up to 500mA, the TPS73512DRBR is versatile enough to meet the needs of a wide range of electronic projects
