Frequently Asked Questions
What output voltage range does the LM828M5X NOPB support?
The LM828M5X NOPB generates an inverted output voltage ranging from -1.8V to -5.5V, making it suitable for powering analog circuits that require a negative supply rail from a positive input source.
How much output current can the LM828M5X NOPB deliver in a portable design?
The device delivers up to 50mA of continuous output current, which is sufficient for most low-power op-amps, ADCs, and signal-conditioning circuits in battery-operated portable equipment operating from a single positive rail.
Why choose the 5-Pin SOT-23 package for space-constrained PCB designs?
The 5-Pin SOT-23 package measures approximately 2.9mm x 1.6mm, occupying very little board area. This miniature footprint is ideal for compact handheld instruments, wearable devices, and multi-layer PCBs where every square millimeter matters.
Does the LM828M5X NOPB require an external inductor to generate a negative voltage?
No, the LM828M5X uses an inverting charge pump topology that operates with only small external capacitors, typically 1µF to 10µF, eliminating the need for an inductor and reducing overall BOM cost and EMI in the design.
