Linear and Low Dropout (LDO) Regulators

Our linear and Low-Dropout Regulators are power supply ICs with a wide range of specifications and performance for consumer, computing, communications, portable, industrial, and automotive applications. They provide a simple, cost-effective way to deliver a regulated output voltage from a higher voltage source.  

Our standard linear regulators include the popular industry-standard 78 series for meeting the needs of many low-cost projects. ZMR and ZSR devices provide local voltage regulation with low quiescent current, making them ideal for low-power applications. The ZXTR products allow for input voltages of 100 volts, which provide unique solutions for industrial and automotive applications.  

Our Low-Dropout Regulators (LDOs) simplify the system design with their low dropout voltages and an array of features that can focus on noise reduction, circuit protection, minimal power consumption, and extremely small footprints. The portfolio encompasses a wide array of capabilities, featuring low IQ LDOs, high PSRR LDOs, wide input voltage LDOs (40v, 45v, 60v), small-size LDOs, high-voltage LDOs, and high-current LDOs. 

The AP7375 has a wide Vin range (3V~45V), 300mA output current, and ultra-low quiescent current (2.1µA). This LDO makes an efficient choice for multi-cell battery-powered equipment.

For the harsh automotive environment, we have developed a portfolio of automotive-compliant LDOs that are AEC-qualified, manufactured in TS16949-certified sites, and support PPAP documents.
