The Texas Instruments TPS7B8650QDDARQ1 is a 500-mA, 40-V, ultra-low-IQ, low-dropout linear regulator specifically designed for automotive applications. Its wide input voltage range, extending up to 40V, allows it to withstand transients common in automotive systems, such as load dumps.
Key electrical specifications include an adjustable output voltage range from 1.2V to 18V, with fixed 3.3V and 5V options available. The regulator boasts a maximum output current of 500mA and a low dropout voltage of 475mV at 450mA. It features excellent line transient response, with ±2% VOUT deviation during cold-crank and ±2% deviation for a 1V/µs VIN slew rate. The quiescent current is remarkably low at 17µA typical at light loads and 5µA maximum when disabled, making it suitable for always-on components.
This device includes a power-good output with a programmable delay period and is stable with a 2.2µF or larger capacitor. It is AEC-Q100 qualified for automotive applications, with a temperature grade of 1 (–40°C to +125°C ambient) and a junction temperature range of –40°C to +150°C.
The TPS7B8650QDDARQ1 is available in an 8-pin HSOIC package with a thermal pad, offering a thermal resistance of 41.8°C/W (RθJA). The mounting type is surface mount.
