TPS7A4701QRGWRQ1 Information

Description

Here's a concise introduction to the TPS7A4701QRGWRQ1: The TPS7A4701QRGWRQ1 is an adjustable low-dropout (LDO) voltage regulator from Texas Instruments (TI). It offers a wide input voltage range of 3V to 35V and can deliver up to 1A of output current. The device features two output voltage modes: ANY-OUT, which allows for user-programmable output via PCB layout, and adjustable operation with an output voltage range of 1.4V to 34V. The TPS7A4701QRGWRQ1 is qualified for automotive applications (AEC-Q100) and features a high level of ESD protection. It also includes built-in fixed current limit and thermal shutdown for added reliability. The device is suitable for various applications, including automotive electronics, industrial automation, telecommunications, precision instrumentation, and control systems.
