LP3891ESX-1.2 Product Details

LP3891ESX-1.2 Overview


A Tape & Reel (TR) case is used to deliver this IC regulator. This voltage regulator IC comes in a TO-263-6, D2Pak (5 Leads + Tab), TO-263BA case. On the regulater IC chip, there are a total of 5 terminations. Output type Fixed. This component features 1 Voltage regulators. As a result of the Linear Voltage Regulator's design, the operating temperature of Surface Mount can be adjusted within a specified range. There is a temperature range of -40°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. A total of 4 pins can be found on the board. 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 5 pins on the chip. As an FYI, this IC voltage regulator has the basic part number LP3891. 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 800mA. It operates in the 7mA Quiescent Current state.
