Frequently Asked Questions
What is the input voltage range of the LM2703MF-ADJ?
The LM2703MF-ADJ operates with an input voltage range of 2.2V to 7V, making it suitable for single-cell Li-ion (3.7V nominal) and dual-cell NiMH battery packs, as well as regulated 5V or 3.3V bus sources in embedded designs.
What control method does the LM2703MF-ADJ use?
The LM2703MF-ADJ uses voltage-mode constant off-time control, which simplifies loop compensation and delivers fast transient response. This technique fixes the switch off-time and varies the on-time to regulate the output voltage, resulting in efficient step-up conversion across a wide load range.
What package does the LM2703MF-ADJ come in and what are its dimensions?
The LM2703MF-ADJ is housed in a 5-pin SOT23 (JESD-30 code R-PDSO-G5) package, an industry-standard small-outline transistor footprint measuring approximately 2.9mm x 1.6mm. This compact package is ideal for space-constrained portable and handheld PCB designs.
Is the LM2703MF-ADJ RoHS compliant?
Yes, the LM2703MF-ADJ carries a Pb-free (RoHS-compliant) designation as indicated by its Pbfree Code 'Yes' and JESD-609 code e0, confirming it meets European RoHS directives and is suitable for lead-free solder assembly processes.
What are typical applications for the LM2703MF-ADJ?
Typical applications include battery-powered portable electronics, IoT sensor nodes, wearable devices, handheld test equipment, and wireless communication modules. Its adjustable output and wide input range make it a versatile boost regulator wherever a low-voltage battery supply must be stepped up to a higher regulated voltage.
