Description

LM3940IT-3.3 Overview
In the case of Tube cases, the regulater IC is delivered. Packaging of the Liner regulator IC takes the form of a TO-220-3 case. The PMIC chip has 3 terminations. Fixed is the Voltage Regulator Chip's output type. Linear IC consists of 1 battery regulators. The range of operating temperatures of Through Hole are programmable in the Voltage Regulator Chip, so that the temperature can be varied as desired. Keeping the temperature at -40°C~125°C degrees is necessary for this regulator to function. There is an output function of Positive configured for this regulator. The sum of the pins in this unit is 3. The part includes 1 outputs in order to ensure that the voltage regulator IC performs effectively and in a timely manner. This voltage regulator IC has a dropout voltage of 10 volts. On the chip, there are pins for the 3 axis. Here's the basic part number for this IC regulator: LM3940. This voltage regulator IC is what is known as a standard Other Regulators component. Upon reaching its maximal output current, 1A, it is able to satisfy the operation requirements. It operates in the 15mA Quiescent Current state.
