Linear voltage regulators for automotive applications
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, AEC-Q100 grade 1 linear voltage regulators offer a wide input range and operate from -40 to +125°C, and from -40 to +175°C for L99VR0 series, ensuring exceptional reliability and safety in extreme conditions. 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.
LDOs functioning either in post-regulation or directly connected to a battery

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. Our LDOs for post regulation are available in a variety of small-footprint packages like the DFN6 (3x3 mm) 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
- High junction temperature and excellent thermal performance (L99VR0 series) for reliable operation in high-temperature environments
Discover the Wettable Flanks (WF) plastic package
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.
