Frequently Asked Questions
What is the input voltage range of the LM2660MM/NOPB?
The LM2660MM/NOPB operates from a minimum input voltage of 1.5V to a maximum of 5.5V, with a nominal operating voltage of 5V. This wide range makes it compatible with both 3.3V and 5V power supply rails commonly used in microcontroller and digital logic systems.
What output current can the LM2660MM/NOPB deliver?
The LM2660MM/NOPB can source up to 100mA of output current. This is sufficient for powering analog front-end circuits, op-amps, LCD bias supplies, and low-power RS-232 transceivers in space-constrained designs.
What external components are required for the LM2660MM/NOPB?
The LM2660MM/NOPB requires only two external capacitors—one reservoir capacitor and one charge pump capacitor—to complete its switched capacitor conversion circuit. No inductors are needed, keeping the BOM minimal and simplifying PCB layout for portable applications.
What are typical applications for the LM2660MM/NOPB?
Typical applications include generating a negative supply rail for op-amps and ADCs from a single positive supply, LCD contrast bias generation, RS-232 signal level conversion, audio circuit dual-supply generation, and power conditioning in IoT sensor nodes and wearable devices.
What package does the LM2660MM/NOPB come in, and is it RoHS compliant?
The LM2660MM/NOPB is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated R-PDSO-G8 per JESD-30. It carries a JESD-609 code of e3, confirming it is lead-free and RoHS compliant, with an estimated end-of-life horizon of 15 years.
