TIP41C TIP41 NPN Power Transistor in Pakistan

AMS1117-5.0V, 1A, SOT-223 Voltage Regulator IC is a series of low dropout three-terminal regulators with a dropout of 5.0V 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 technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on demand, such as 1%.

The LM7805CV is a fixed output, three-terminal precision positive voltage regulator in 3 pins TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single-point regulation. The L7805 fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits the maximum current the circuit will pass, and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 1A output current.

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.
