4072 IC Dual 4 Input OR Gate In Pakistan

AMS1117-ADJ 1A, SOT-223 Voltage Regulator IC is a series of low dropout three-terminal regulators with a dropout of adjustable Voltage at 1A load current. AMS 1117 features a very low standby current of 2mA compared to the 5mA of a competitor. Other than a fixed version, Vout = 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V, and 12V, AMS1117 has an adjustable version, which can provide an output voltage from 1.25 to 12V with only two external resistors. AMS 1117 offers thermal shut down and current limit functions, to assure the stability of the chip and power system. And it uses a trimming techncation of ique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on-demand, such as 1%.

These devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

The LM193 device is characterized for operation from 55C to 125C. The LM293 and LM293A devices are characterized for operation from 25C to 85C. The LM393 and LM393A devices are characterized for operation from 0C to 70C. The LM2903 device is characterized for operation from 40C to 125C.

The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed a maximum of 1.3V, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1.5%. The current limit is set to minimize the stress under overload conditions on both the regulator and power source circuitry. The AMS1117 devices are pin-compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package, in the 8L SOIC package, and in the TO-252 (DPAK) plastic package.
