Capable of output 5 volts low voltage difference regulator Foreign integrated voltage regulator chip models include but are not limited to LM2576-LT1086-AMS1117-5 and so on. These chips are industry-renowned integrated voltage regulators low voltage differential regulator chips and have stable output voltage performance. An integrated voltage regulator chip is an electronic component used to convert an unstable input voltage into a stable output voltage.
TL431 is an adjustable product produced by Texas Instruments (TI)The output voltage is continuously adjustable in the range of 5~36V. The circuit symbol, pin arrangement, equivalent circuit and basic wiring diagram of TL431 are shown in Figure a, b, c and d respectively. In Figure b, A is the anode, grounding low voltage difference regulator chip when in use; K is the cathode, which needs to be connected to the positive power supply through the current limiting resistance; R is the output voltage VO setting end, the external resistor voltage.
The XC6206 series is a high-precision, low-power, 3-pin LDO high-voltage regulator chip that uses CMOS technology and laser fine-tuning technologyIn the case of large output current, the input-output pressure difference can also be small. The XC6206 series chip includes a current limiting circuit, a drive triode, a high-precision reference voltage source and an error correction circuit.
The BR431 is an integrated circuit, similar to the common 9013 triode, used to generate an accurate reference voltage of 5 to 37 volts. The TL431 is the most common model, while the BR431 is the domestic version. The two are identical in performance parameters and can be used interchangeably.
Use the lm78/lm79 series three-terminal voltage regulator IThe peripheral components required to form a voltage regulator power supply are very few, and there are overcurrent, overheating and regulating tube protection circuits inside the circuit, which are reliable, convenient and cheap to use. The numbers after lm78 or lm79 in this series of integrated voltage regulator IC models represent the output voltage of the three-terminal integrated voltage regulator circuit, such as lm7806 indicating a positive output voltage of 6V and lm7909 indicating a negative output voltage of 9V.
For example, the model 7805 integrates a three-terminal regulator with a fixed 5V output. Adjustable output voltage regulator The output voltage can be adjusted over a wide range with a few external components,When the value of the external element is adjusted, the desired output voltage is obtained. For example, Low voltage difference regulator chip : CW317 type integrated three-terminal regulator, the output voltage can be continuously adjustable in the range of 12 ~ 37V.
1. sj112 and 2sj113 are interchangeable. The above SC662K-3 chip belongs to the low voltage differential regulator IC Low voltage differential regulator chip , S0T23-3 package, its parameter is 3Ⅴ/250mA. About the above low voltage difference regulator chip The 1117-3 chip is also a low voltage difference regulator IC, SOT-223 package, its parameter is: 3V/1000mA. Power transistor used: The power transistor used by the low-voltage differential regulator can be a bipolar transistor or a field-effect transistor.
2, depending on the load, 7133 maximum output current is generally 50-100mA,The maximum output current of the 1117 can reach 1A. If the back-end load is particularly small, for example, there is only one single chip microcomputer or its low voltage differential regulator chip other chip, it can be replaced.
3, -3 power module itself consumes power. 1117-3 belongs to the series stabilized power supply. The higher the input voltage, the greater the power P= (Vin-3) * I carried by the device itself. Therefore, the lower the input voltage, the better. If the input voltage is 6V, the power consumption of the load is equal to that of the power supply, and the efficiency is 50%. Device input and output voltage difference Vdropout (Vin-Vout) range is approximately 0.8-2.
