Low-noise LDO regulator
14 November 2018, Power Electronics / Power Management

The STMicroelectronics LDO40L 400 mA low-dropout linear regulator delivers quiet and efficient power for always-on automotive modules and noise-sensitive loads.

With 45 μA quiescent current, the AEC-Q100 qualified device reduces the demand on vehicle batteries to run loads such as body and interior functions that are active when the ignition is off. In addition, the device can be disabled to achieve a very low shutdown current of only 1 μA.

The internal circuity operates from an input voltage as low as 3,5 V and combined with the extremely low dropout voltage of 36 mV at 100 mA load, or 140 mV at full load, this enables the LDO40L to maintain power to the load as the input dips during cold cranking.

In addition to powering automotive body-control modules, instruments and clusters, and LED lighting, the LDO40L also ensures stable, high-quality DC for industrial controls and building- or home-automation applications. Output noise is just 20 μV, power supply rejection ratio (PSRR) 70 dB @1 kHz, and protection features including current limit and thermal shutdown are built-in.

The device variants give a choice of fixed 3,0 V, 3,3 V, 5,0 V or 8,5 V output voltage, regulated within ±3% including line, load and temperature variation. Only two capacitors are needed to complete the application circuit. An adjustable-output version is also available, which allows designers to set a desired output voltage down to 2,5 V minimum using an external resistor divider.

All versions are housed in a 3 x 3 mm DFN6 package with wettable flanks, which is smaller than the DPAK outline of typical competing devices yet maintains high thermal performance and excellent reliability in relation to heatsink size.
