Frequently Asked Questions

What are the output voltage ranges of the LM26480SQ-AA/NOPB?

The LM26480SQ-AA/NOPB features two independently adjustable output channels: Channel 1 supports 0.8V to 2V, and Channel 2 supports 1V to 3.3V. Both channels can deliver up to 1.5A of output current, making it suitable for dual-rail power supply designs.

What input voltage range does the LM26480SQ-AA/NOPB support?

The LM26480SQ-AA/NOPB operates with an input voltage range of 2.8V to 5.5V, with a nominal input of 3.6V. This range is compatible with single-cell Li-ion batteries and standard 3.3V or 5V supply rails commonly used in embedded and portable systems.

What control modes are available on the LM26480SQ-AA/NOPB?

The LM26480SQ-AA/NOPB supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) control techniques under voltage-mode control. PFM mode improves light-load efficiency, while PWM mode ensures stable regulation under heavier loads—giving designers flexibility to optimize for efficiency or noise performance.

What package does the LM26480SQ-AA/NOPB come in, and is it RoHS compliant?

The LM26480SQ-AA/NOPB is housed in a 24-pin Quad Flat No-Lead (QFN) package, which offers a compact footprint ideal for space-constrained designs. It is Pb-free and RoHS compliant, as indicated by its NOPB suffix and Pbfree Code: Yes specification.

What applications is the LM26480SQ-AA/NOPB best suited for?

The LM26480SQ-AA/NOPB is ideal for dual-rail power management in IoT devices, wearables, smartphones, wireless communication modules, and automotive infotainment systems. Its adjustable dual-output LDO design with PFM/PWM flexibility enables efficient regulation across a wide range of load conditions and battery-powered use cases.
