LM7812ACT Product Details

LM7812ACT Overview


A Tube case is used to deliver this IC regulator. This voltage regulator IC comes in a TO-220-3 case. On the regulater IC chip, there are a total of 3 terminations. Output type Fixed. This component features 1 Voltage regulators. As a result of the Linear Voltage Regulator's design, the operating temperature of Through Hole can be adjusted within a specified range. There is a temperature range of 0°C~125°C degrees during operation of the IC regulator. There is a configuration in this voltage regulator IC that specifies that its output function is Positive. In order to deliver prompt, sufficient and reliable performance, this regulator IC has 1 outputs in total. A dropout voltage of 10 volts can be obtained from this voltage regulator IC. There are 3 pins on the chip. As an FYI, this IC voltage regulator has the basic part number LM7812. As you can see from the picture, the regulator IC is packed in a certain way. Taking into account the operation requirements, the maximum output current of the IC voltage regulator reaches 1A. It operates in the 6mA Quiescent Current state. The top supply voltage can be set to 27V volts.
