Flyer Linear Voltage Regulators
Software tools like Spice are widely used in electronics design and useful for simulation and optimization of circuits. Often the theoretical behaviour is, however, not matching to the later on real life testing, which requires in worst case a time consuming re-design. One reason for such mismatch is the lack of comprehensive thermal characteristics in Spice models, as offered by many suppliers. While e. g. the temperature behaviour of forward voltage and reverse leakage of semiconductor diodes are part of almost every Spice model, it is seldom provided for the voltage drift of Zener and TVS diodes, or the presumed constant current of CLDs (Current Limiting Diodes). And exactly that can cause an issue, when later the device is operated in the real circuit and gets unavoidable warm under load.
The Spice models provided by Diotec for its Zener and TVS diodes, CLDs but of course also all rectifiers are made with additional temperature characterisation.
Provided that Spice simulation is done with different temperature presettings, one can see the behaviour under real junction conditions and can adjust the circuit where necessary. The picture shows as an example the temperature behaviour of an uncompensated and a compensated CLD.
Spice models for Diotec products are accessible via www.diotec.com using simply the part search function.

LDI812C-3.3SFA: 超低功耗LDO - 用于低功耗电子器件的高精度和高性能
The Internet of Things is constantly evolving all around the world. Many of these devices are compact, wearable, battery powered or integrated into consumer and industrial electronics. Minimizing the battery discharge is an essential need for keeping these electronic gadgets work for long durations. It requires LDOs with very low quiescent currents, for minimizing power consumption during stand by mode.
The LDI812C-3.3SFA from Diotec is a CMOS based high voltage low-dropout positive voltage regulator, specifically designed for low-power electronics and battery operated systems where power savings are decisive. This device can be operated at a wide range of input voltage up to 16 V. It features a fixed output voltage of 3.3 V and output current rating of 50 mA. Dropout voltage is as low as 230 mV and quiescent current ultra-low at typically 1 µA.
The device facilitates minimal board space due to its small outline dimensions and a potentially smaller output ceramic capacitor of 1.0 µF.

几乎所有类型的TVS二极管应用 - 绿色和可持续技术的高性能保护
To design sustainable or "green" technologies means also to ensure longest possible lifetimes of electronic devices, once they are produced. An important item is here the protection against transient voltage peaks, as they occur on the power grid in case of lightning strikes. Transient Voltage Suppressors (TVS) prevent high voltage surges from damaging sensitive electronic circuits. Diotec offers TVS Diodes for almost all kind of applications, and from low up to very high voltage levels. Check out our latest Application Note to find the optimal TVS solution for your project.
