TL431 Adjustable Precision Shunt Regulator TO-92 Package

The adjustable and fixed voltage regulators of the AMS1117 series are designed to deliver 1A output current and function down to 1V input-to-output difference. The device's dropout voltage is guaranteed to be 1.3V at maximum output current, dropping at lower load currents. Trimming on-chip adjusts the reference voltage to one percent. The current limit is also reduced, reducing stress on the regulator and energy source circuitry under overload conditions. The AMS1117 devices are pin compatible with existing three-terminal SCSI regulators and are available in low-profile surface mount SOT-223 packages, 8L SOIC packages, and TO-252 (DPAK) plastic packages.

The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators

Features of LM7824 IC? include: internal thermal overload protection, internal short circuit current limiting, output transistor safe-area compensation, output current in excess of 1.0 A, no other components needed. Voltage at output Available in Surface Mount D2PAK3, DPAK3, and Standard 3 Lead Transistor Packages; Offered in 1.5 percent, 2 percent, and 4 percent Tolerance; NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q100 Qualified and PPAP Capable; These are Pb-Free Devices

The MIC4576 is a series of easy-to-use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200 kHz MIC4576 duplicates the pinout and function of the 52 kHz LM2576. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size. The MIC4576 is available in 3.3V, and 5V fixed output versions or a 1.23V to 33V adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation. The feedback voltage is guaranteed to ?2% tolerance for adjustable versions, and the output voltage is guaranteed to ?3% for fixed versions, within specified voltages and load conditions. The oscillator frequency is guaranteed to ?10%. In Shutdown mode, the regulator draws less than 200 ?A shutdown current. The regulator performs cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. This series of simple switch-mode regulators requires a minimum number of external components and can operate using a standard series of inductors. Frequency compensation is provided internally. The MIC4576 is available in TO-220 (T) and TO-263 (U) packages for the industrial temperature range.
