ST’s linear regulator portfolio provides the best answer to any clean power supply requirement. It doesn’t matter which performance you are looking for, a solution is always available among our products! In addition to the well-recognized leadership and outstanding quality of our standard regulators for both positive and negative outputs, the ever-expanding high performance families address all the major trends in the modern industrial era. Our portfolio is the striking result of ST continuous improvement activity as well as the unrestrained research for the best performance – be it the lowest possible dropout voltage and quiescent current or the best transient response, ripple rejection and low noise.

Make sure the voltage reference you are looking for is a real reference in the market! Need to design a simple wall adapter or an ultra-precise robot for non-invasive surgery?...Don’t worry! ST provides you with the best solution and no compromises. Inside the ST portfolio a wide range of fixed and adjustable voltage references ranging from general-purpose high power shunts, suitable for industrial and SMPS applications coexists with a selection of state-of-the art high-precision and low-consumption devices, suitable for battery-powered applications or high-accuracy equipment working in sensitive environments such as automotive and avionics or laboratory instrumentation.

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).

Car LED lights need switching power supplies with rather large current for their size. Plug and power adapters for portable appliances and DC/DC point-of-load (POL) modules have the same need for compactness. The small size itself is a goal, and the consequence is a need for very small power losses as the space-consuming heatsinking is kept to a minimum. Water-resistant enclosures further allow for reduced heat sinking.

For these applications, STMicroelectronics recently developed an essential complement to the SMD range of low voltage drop, low leakage Schottky diodes. The SMA Flat, SMB Flat, PowerFlat, SOD-123 and SOD-128 Flat devices make room for 1 to 8 A, 30 to 150 V switcher designs at a budget compatible with these applications. Datasheets that include helpful thermal impedance values and avalanche pulse curves are available for engineers to fine-tune their designs to ensure a robust finished product.

In H1 '20 ST is introducing the new range of SMA & SMB Flat 1 mm surface mount Schottky rectifiers from 1 to 5 A allowing automated assembly. With the new SMA & SMB Flat footprint, compatibility with SOD-128, SMA and SMB and therefore procurement flexibility has been maintained. The range of Schottky in SMA & SMB Flat package reduces the thickness by half compared to the standard SMA & SMB package range.

This brings compactness in lighting and adapter designs as well as industrial equipment with high power density specification. These 1 to 5 A Schottky diodes have voltages ranging from 30 to 170 V (SMA Flat) / 40 to 200 V (SMB Flat). ST Schottky diodes all have specified avalanche characteristics.

ST’s T-series Triacs are designed for the ever increasing number of AC loads in appliance control. These AC appliance switches meet both the immunity and high-commutation needs, offering a cost-effective solution. For this series, both immunity (dV/dt) and commutation capability (dI/dt)c are specified, as well as the low gate current. This last parameter is key, as it helps optimize the power supply and allows direct drive capability through a single resistance between the microcontroller and the Triac, for all 10 mA gate types. 

6 to 20 A T-series Triacs with 35 mA gate types and 800 V capability are now available in a D²PAK package, providing improved EMC immunity and commutation for a wider range of loads. The trade-off of surge current (I TSM) versus immunity and commutation capability is improved. This is one step ahead of the usual offer, and a unique range in the market. Designers can now use our online Triac / AC switch simulator to get design characteristics and select the best device for your application.
