Frequently Asked Questions
What is the output voltage range and how is it adjusted on the LP3878MR-ADJ/NOPB?
The LP3878MR-ADJ/NOPB features a fully adjustable output voltage ranging from 1V to 5V, set by an external resistor divider connected to the ADJ pin. The output voltage is determined by the ratio of two resistors, allowing designers to dial in any target voltage within the range with high precision.
What input voltage and output current does the LP3878MR-ADJ/NOPB support?
The device accepts an input voltage from 2.5V to 16V and delivers up to 800mA of continuous output current. With a typical dropout voltage of only 0.475V, it maintains regulation even when the input-output differential is small, making it highly efficient for battery-powered designs.
Is the LP3878MR-ADJ/NOPB compatible with ceramic output capacitors?
Yes, the LP3878MR-ADJ/NOPB is specifically designed to be ceramic-stable, meaning it remains stable with low-ESR ceramic capacitors at the output. This is a key advantage over many LDOs that require tantalum capacitors, reducing BOM cost and PCB space in consumer and industrial applications.
What package does the LP3878MR-ADJ/NOPB come in, and where can I buy it?
The LP3878MR-ADJ/NOPB is available in an 8-pin Small Outline (SOIC-8) package with JEDEC code R-PDSO-G8, suitable for surface-mount assembly. It is RoHS-compliant (Pb-free, e3 rated) and can be purchased starting from approximately $0.76 per unit with worldwide shipping available.
