L4931CD40 Product Details

L4931CD40 Overview


Packaging of the Liner regulator IC takes the form of a SO case. The PMIC chip has 8 terminations. Fixed is the Voltage Regulator Chip's output type. Currently, 250mA are being output by it at the moment. The sum of the pins in this unit is 8. 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. This voltage regulator IC is what is known as a standard Other Regulators component. Upon reaching its maximal output current, 250mA, it is able to satisfy the operation requirements. In the event that the temperature in your room falls below 125°C, then this feature should be used at such a time. During the operation of the chip, the chip's operating temperature is not less than -40°C degrees. In general, this voltage regulator IC will output 4V volts when used as a system part.
