Product highlights
AEC-Q100-qualified and low-noise, the LD49100 dropout voltage linear regulator is ideal for multiple automotive applications, including in-cabin ECUs.
Ultra-low quiescent current of 5 μA combined with 28V input voltage make the ST732 suitable for always-on applications, such as smart meters, smoke detectors and industrial machines
The ST730 is a 300mA, 28 V LDO regulator with embedded protection functions, featuring ultra-low quiescent current of 5 μA suitable for electronic applications which are always turned on.
Housed in a compact package, the LD57100 voltage regulator for battery-operated devices features ultra-low dropout voltage at 1 A load. Thermal protection and shutdown mode included.
The LM217M and LM317M are monolithic integrated circuits in DPAK and SOT223 packages used as positive adjustable voltage regulators.
The LM4040 is a low power and high accuracy shunt voltage reference providing a stable output voltage over the industrial temperature range (-40 °C to +125 °C), with a maximum temperature coefficient of 70 ppm/°C.
ST's Amplifier and Comparator portfolio includes a broad range of general-purpose and industry-standard, pin to pin replacement products, like the popular LM3 and LM29 series, up to 44 V op amps, as well as TL06/07/08 series of junction field-effect transistor (JFET) low input bias current op amps. Many references are available with automotive-grade qualification (AEC-Q100-compliant) and they all provide the highest quality and robustness. ST op amps help enhance the signal chain and are the perfect companion to microcontrollers and analog sensors.
ST offers interface ICs complying with the most popular industry-standard protocols including RS-232, RS-422, RS-423, and RS-485. They are available in a choice of transmitter/receiver configurations with data rates up to 30 Mbit/s. To meet requirements for the harsh industrial environment, they are available in a 3 to 5.5 V operating voltage range with enhanced ESD protections (15 kV HBM, 8 kV contact discharge) and extended temperature range (-40 to 125°C).
