Three terminal voltage regulator is also known as the three terminal regulator or regulator. Three terminal regulator is one of the electronic integrated circuit IC tage category in the main product. The three terminal regulator effectively using several fixed voltage to obtain a wide scope of application, can replace the zener diode and the resistor mixed, quiescent current and gain lower. 100mA suitable for all kinds of voltage regulator requirements. NSP-78L series voltage regulator package all the use of S0T-89, output voltage 5.0V, 6.0V, 8.0V, 9.0V, 12V, 15V, can be used in the logic system, testing instruments, HIFI, and other ideas equipment. Can replace the overheating protection IC. NSP-78L05 is one of the commonly used voltage regulator tube in smart meters. NSP2951 series, respectively, to improve the SOT-23 and SOT-89 two packages, with: 1, low dropout; 2, low leakage current; 3, resistance to high pressure; 4, small size and other characteristics.
Electronic products, the common three terminal voltage regulator IC has a positive voltage output of 78 x x series and 79 x x x x x x x x x X X. As the name suggests, the three terminal IC is the voltage regulator with the integrated circuit, only three pin output, respectively, the input, the ground and the output terminal. It looks like a common transistor, TO- 220 standard package, there are 9013 look TO-92 package. With 78/79 series three terminal regulator IC to form the required peripheral components of a regulated power supply is very few, the circuit inside and over current, over heat and adjust the protection circuit, the use of reliable and convenient, and the price is cheap. The series integrated voltage regulator IC model of 78 or 79 in the back of the digital representation of the three terminal integrated voltage regulator circuit output voltage, such as 7806 indicates that the output voltage is positive 6V, 7909 indicates that the output voltage is negative 9V.

Voltage regulator tube type designation method:
Model for example: NSP-78L05-T
1, NSP-78L: three terminal voltage regulator type
2, 05: voltage 5V
3, T: packaging for the tape packaging. Default state default for tape wrapping.
4, package size: SOT-89

What are the main parameters and characteristics of NSP three terminal voltage regulator?
Three terminal regulator use several fixed voltage to obtain a wide scope of application, can replace the zener diode and the resistor mixed, and lower static current. 100mA suitable for all kinds of voltage regulator requirements. These voltages can be used in logic systems, instrumentation, HIFI, and other ideas for the device. Can replace the overheating protection IC. Taking NSP-78LXX as an example, the main parameters are as follows
Output voltage accuracy 5%
Output current 100mA
Built in over current protection function
Output voltage 5.0V, 6.0V, 8.0V, 9.0V, 12V, 15V

Three terminal voltage regulator selection considerations:
Three terminal regulator / regulator of the absolute maximum value is a limit value, in any case, even a very short period of time will not be exceeded. Moreover, the absolute value of any two items can not be reached at the same time limit. Any beyond the maximum operation, will cause permanent damage to the device. This is only an important range value, but does not mean that all the functional operations must be done in this limit.
