LM63625-Q1
The LM63625-Q1 is a high-performance, low-dropout linear regulator (LDO) designed for automotive applications, offering exceptional stability and efficiency under demanding conditions. It delivers a maximum output current of 2.5 A with a dropout voltage as low as 300 mV at full load, making it ideal for power-sensitive systems where voltage headroom is limited. The device operates from an input voltage range of 4.5 V to 28 V, supporting wide VIN compatibility across various automotive power domains such as battery, alternator, and start-stop systems.
This LDO features built-in protection mechanisms including over-current protection (OCP), thermal shutdown, and reverse battery protection, ensuring robust operation in harsh environments typical of automotive electronics. Its ultra-low quiescent current—typically 70 µA—enhances system efficiency during idle or sleep modes, which is critical for meeting stringent power management standards in modern vehicles. Additionally, the LM63625-Q1 includes a precision reference voltage (±1%) and fast transient response, enabling stable regulation even under rapidly changing load conditions.
Designed to meet AEC-Q100 Grade 1 qualification requirements, the LM63625-Q1 is suitable for use in safety-critical applications such as infotainment systems, ADAS (Advanced Driver Assistance Systems), body control modules, and telematics units. Its compact 8-pin PowerPAD™ package improves thermal performance by efficiently dissipating heat through the PCB, allowing reliable operation in confined spaces typical in automotive designs.
The device also supports soft-start functionality to minimize inrush current during startup, reducing stress on the power supply and connected components. With a wide operating temperature range from –40°C to +125°C, it ensures consistent performance across extreme environmental conditions, from cold winter starts to high-temperature engine bay operation. Furthermore, its pin-to-pin compatibility with other TI LDOs simplifies design migration and reduces development time for engineers working on multiple platform variants.
In summary, the LM63625-Q1 provides a robust, efficient, and reliable solution for automotive power management, combining advanced protection features, excellent thermal performance, and compliance with industry standards for safety and durability.
