A full set of high-performance voltage regulators for wide range of applications
ST's low-dropout (LDO) linear voltage regulators are specifically designed to meet the stringent performance and safety standards of the automotive industry ensuring stable and reliable power supply. Our high-performance linear voltage regulators, AEC-Q100 grade 1 qualified feature a wide input range and an ambient temperature range of –40 to +125°C, while offering exceptional reliability and safety. They can be used for a broad range of automotive applications such as ADAS, body control modules (BCM), electric vehicles (EV) battery-management systems and powertrain, infotainment, and instrumentation clusters.
Ultra-low dropout regulators for direct conversion from car battery
Ensure maximum efficiency and minimal power consumption
Ensure maximum efficiency and minimal power consumption
Our ultra-low dropout regulators are specifically designed for battery-connected automotive applications. These voltage regulators boast an ultra-low quiescent current, making them ideal for always-on devices or standby mode.
LDOs for post regulation
Enhance noise-sensitive loads with low noise and small packages solutions
Enhance noise-sensitive loads with low noise and small packages solutions
Low-quiescent current and low-noise features make our ultra-low dropout regulators the perfect choice for automotive post-regulation. Our LDOs for post regulation are available in a variety of small-footprint packages like DFN6 (3x3 mm) package with wettable flanks.
Key features
- Ease of use since most of the ST’s LDOs are also available in fixed-output configurations for an easy board implementation
- High PSRR and low noise for cleaner and stable output voltages, especially suitable for ultra-sensitive loads
- Low quiescent current for lower power consumption during standby or sleep mode
- Wettable flank-plated DFN and small packages to ensure high-reliability and to reduce the board size

These new packages feature a unique mounting edge design that includes fillet termination, enabling automated optical inspection (AOI) to confirm proper pad connection. This is particularly useful as the pad is typically obscured once the device is soldered onto a board.
