What are the key features of MAQ5280YME?
- Adjustable LDO with 1.215 V to 5 V output range and ±3% accuracy covering a wide set of analog and digital bias rails
- 25 mA output current capability with 1.5 V maximum dropout voltage in a compact SOIC-8 footprint
- -40°C to 125°C operating temperature range qualifying it for automotive and industrial environment use
What is MAQ5280YME used for?
MAQ5280YME is used to generate precision reference and bias voltages for analog front ends, ADC reference rails, and operational amplifier supply rails in industrial sensors and automotive control modules. Its adjustable 1.215 V to 5 V output covers most low-current analog supply needs with a single device, eliminating dedicated reference ICs in cost-sensitive designs. The wide -40°C to 125°C temperature range makes it suitable for under-hood automotive applications and outdoor industrial instrumentation exposed to harsh thermal environments.

Frequently Asked Questions
How is the output voltage of MAQ5280YME adjusted, and what external components are required?
MAQ5280YME output voltage is set by a resistor divider from the output to the ADJ pin, following the standard LDO adjust formula. Two resistors in the 10 kΩ to 100 kΩ range are sufficient to program any voltage between 1.215 V and 5 V, consuming only a few microamps of quiescent divider current that is negligible relative to the 25 mA load capability.
What is the significance of the 1.5 V maximum dropout voltage for MAQ5280YME in a 3.3 V input to 1.8 V output design?
With a 1.5 V maximum dropout, MAQ5280YME can regulate a 1.8 V output from inputs as low as 3.3 V, which is well within the 1.5 V headroom available. This makes it directly usable on 3.3 V logic rails to generate 1.8 V analog supply without a switching pre-regulator, keeping the BOM simple and solution noise low for sensitive RF and ADC bias circuits.
In what scenarios does MAQ5280YME operating from -40°C to 125°C provide a key advantage over commercial-grade LDOs?
Commercial-grade LDOs rated only to 85°C may exceed their junction temperature limit in automotive engine-bay ECUs or industrial field transmitters where ambient temperature reaches 105°C. MAQ5280YME's -40°C to 125°C range ensures stable 25 mA regulation and ±3% output accuracy through full temperature excursions, meeting AEC-Q100 Grade 1 equivalent thermal stress requirements without derating.
