The ATL431 is three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and industrial temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. These devices have a typical output impedance of 0.05 Ω.
Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable powersupplies, and switching power supplies.
The ATL43x has > 20x improvement cathode current range over it's TL43x predecessor. It also is stable with a wider range of load capacitance types and values.
ATL431 is the exact same parts but with different pinouts and order numbers. The ATL43x is offered in two grades, with initial tolerances (at 25°C) of 0.5%, 1%, for the B and A grade, respectively. In addition, low output drift vs temperature ensures consistent voltage regulation over the entire temperature range.
Part Number : LM4040DIM3-2.5/NOPB

Ideal for space-critical applications, the LM4040-N precision voltage reference is available in the subminiature SC70 and SOT-23 surface-mount package.
The advanced design of the LM4040-N eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4040-N easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 3 V, 4.096 V, 5V, 8.192 V, and 10 V. The minimum operating current increases from 60 μA for the 2.5-V LM4040-N to 100μA for the 10-V LM4040-N. All versions have a maximum operating current of 15 mA.
The LM4040-N uses a fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.
Also available is the LM4041-N with two reverse breakdown voltage versions: adjustable and 1.2 V.

Infineon’s EZ-USB FX3 is a SuperSpeed peripheral controller, that provides integrated and flexible features.
FX3 has a fully configurable, parallel, general programmable interface called GPIF II, which can connect to any processor, ASIC, or FPGA. GPIF II is an enhanced version of the GPIF in FX2LP, Infineon’s flagship USB 2.0 product.
It provides easy and glueless connectivity to popular interfaces, such as asynchronous SRAM, asynchronous and synchronous address data multiplexed interfaces, and parallel ATA.
FX3 has integrated the USB 3.2 Gen 1 and USB 2.0 physical layers (PHYs) along with a 32-bit ARM926EJ-S microprocessor for powerful data processing and for building custom applications. It implements an architecture that enables 375-MBps data transfer from GPIF II to the USB interface.
An integrated USB 2.0 OTG controller enables applications in which FX3 may serve dual roles; for example,EZ-USB FX3 may function as an OTG Host to MSC as well as HID-class devices.
FX3 contains 512 KB or 256 KB of on-chip SRAM (see “Ordering information” on page 67) for code and data.
