LM1086 1.5-A Low Dropout Positive Voltage RegulatorsDescription:The LM1086 is a regulator with a maximum dropout of 1.5 V at 1.5 A of load current. The device has the same pin-out as TI's industry standard LM317. Two resistors are required to set the output voltage of the adjustable output voltage version of the LM1086. Fixed output voltage versions integrate the adjust resistors. Typically, no input capacitor is needed unless the device is situated more than 6 inches from the input filter capacitors. Output capacitor can be replaced with ceramic and appropriate ESR. The LM1086 circuit includes a zener trimmed bandgap reference, current limiting, and thermal shutdown. Because the LM1086 regulator is floating and detects only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded. Exceeding the maximum input-to-output deferential will result in short circuiting the output. By connecting a fixed resistor between the adjustment pin and output, the LM1086 can be also used as a precision current regulator. For applications requiring greater output current, refer to LM1084 (clickable link) for the 5-A version, and the LM1085 (clickable link) for the 3-A version.Features:• Available in 3.3-V, 5.0-V, 12-V and Adjustable Versions• Current Limiting and Thermal Protection• 2% Output Accuracy• Output Current 1.5 A• Line Regulation 0.015% (Typical)• Load Regulation 0.1% (Typical)• Maximum Input Voltage up to 29V• Minimum Adjustable Output Voltage Down to 1.25V• Stable with Ceramic Output Capacitor with ESR• Temperature Range : -40°C to 125°CApplications:• High Efficiency Linear Regulators• Battery Charger• Post Regulation for Switching Supplies• Constant Current Regulator• Microprocessor Supply• Audio Amplifiers Supplies• Fire Alarm Control

Low-dropout voltage regulator, +2.5 V, 0.5 AEnclosure: TO-220

The LM2937 is a positive voltage regulator capable of supplying up to 500 mA of load current. The use of a PNP power transistor provides a low dropout voltage characteristic. With a load current of 500 mA the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5 V (1-V ensured maximum over the full operating temperature range). Special circuitry has been incorporated to minimize the quiescent current to typically only 10 mA with a full 500-mA load current when the input to output voltage differential is greater than 3 V.

DescriptionThe ’HC597 and CD74HCT597 are high-speed silicon gate CMOS devices that are pin-compatible with the LSTTL 597 devices. Each device consists of an 8-flip-flop input register and an 8-bit parallel-in/serial-in, serial-out shift register. Each register is controlled by its own clock. A “low” on the parallel load input (PL) shifts parallel stored data asynchronously into the shift register. A “low” master input (MR) clears the shift register. Serial input data can also be synchronously shifted through the shift register when PL is high.
