Frequently Asked Questions
What output voltages does the LM2773TL/NOPB support?
The LM2773TL/NOPB provides 1.8 V and 1.6 V regulated output voltages, with an additional 1.815 V output option noted as a feature. These output options support common low-voltage digital and RF circuit power rail requirements in portable devices.
What is the input voltage range of the LM2773TL/NOPB?
The LM2773TL/NOPB accepts an input voltage from 2.5 V minimum to 5.5 V maximum, with a nominal input of 3.6 V. This range is compatible with single-cell lithium-ion batteries and standard USB power sources commonly used in portable electronics.
Why does the LM2773TL/NOPB use spread-spectrum modulation?
The spread-spectrum pulse frequency modulation technique distributes switching noise energy across a broader frequency band, significantly reducing peak EMI emissions. This makes the LM2773TL/NOPB ideal for RF-sensitive and audio applications where switching regulator noise can degrade system performance.
What package does the LM2773TL/NOPB use and is it lead-free?
The LM2773TL/NOPB is housed in a 9-ball BGA package (JESD-30 code S-PBGA-B9), which is a small, low-profile surface-mount package suitable for compact PCB designs. It is lead-free (Pb-free Code: Yes), confirming RoHS compliance for environmentally regulated markets.
