ST offers a wide range of low and medium power LDO regulators featuring ultra-low dropout and fast transient response characteristics. The ultra-low dropout series of LDOs simplifies the design of high-efficiency, cost-effective linear power management (from 50 mA to 3 A of continuous load current), ideal for DSPs, MCUs and FPGAs.

New LDO with extended input voltage range features ultra-low dropout and low consumption
The LDO40L is a 400 mA low dropout linear regulator designed for use in harsh automotive and industrial environments. A low operating quiescent current of 45uA makes the device suitable for always-on automotive applications such as in body and interior functions active during car parking.
Able to start up with an input voltage of just 3.5V and operates with up to 38V, the LDO40L ensures correct regulation in applications with wide variations of the power rail (i.e. cold-crank in automotive, unregulated DC rails in industrial applications). Featuring a high PSRR of 70 dB @ 1 kHz and low intrinsic noise performance of 20 µVRMS/VOUT, this ultra-low-dropout regulator is available in a 3 x 3 mm DFN6 package with wettable flanks and is automotive-grade qualified according to AEC-Q100 Level 1.
