Frequently Asked Questions
What is the output current and dropout voltage of the REG104GA-AG4?
The REG104GA-AG4 provides up to 1A of output current with a typical dropout voltage of 0.23V (maximum 0.4V) at full load. The low dropout voltage means it can regulate efficiently even when the input voltage is only slightly higher than the output voltage.
Is the output voltage of the REG104GA-AG4 fixed or adjustable?
The REG104GA-AG4 has an adjustable output voltage, set by an external resistor divider connected to the feedback pin. This allows designers to configure the output voltage to meet specific load requirements within the supported input range of 2.7V to 15V.
What package is the REG104GA-AG4 available in?
The REG104GA-AG4 is packaged in a 6-pin SOT-223 (JEDEC R-PDSO-G6) surface-mount package. This package includes a large exposed tab for improved thermal performance, allowing higher output currents without exceeding junction temperature limits.
Is the REG104GA-AG4 RoHS compliant?
Yes, the REG104GA-AG4 carries the DG4 suffix and JESD-609 code e4, confirming it is a Green, RoHS-compliant, lead-free device. It meets current environmental regulations for electronics sold in major global markets.
