Applications
The LP2985AIM5-2.8 is well suited for powering RF transceivers, Bluetooth modules, and sensor subsystems in portable consumer electronics where board space is limited. Its low dropout voltage maximizes battery life in Li-ion powered devices, while the fixed 2.8V rail directly supplies common RF front-end and MCU I/O voltages. It is also widely used in industrial handheld instruments and wearable devices that require a stable, low-noise supply from a compact regulator.

Frequently Asked Questions
What is the output voltage and maximum output current of the LP2985AIM5-2.8?
The LP2985AIM5-2.8 provides a fixed 2.8V output voltage with a maximum output current of 150mA. The nominal dropout voltage is 0.28V, meaning the input supply must be at least 3.08V to maintain regulation at full load.
What input voltage range is supported by the LP2985AIM5-2.8?
The LP2985AIM5-2.8 accepts an input voltage from 3.8V minimum up to 16V absolute maximum, making it compatible with single-cell Li-ion batteries, 5V USB rails, and 12V industrial supplies.
What package does the LP2985AIM5-2.8 use, and is it suitable for compact designs?
The LP2985AIM5-2.8 comes in a SOT-23-5 (JESD-30 code R-PDSO-G5) 5-pin small-outline package. This footprint is ideal for space-constrained PCB layouts in wearables, IoT sensors, and portable instruments.
Can the LP2985AIM5-2.8 replace other 2.8V LDO regulators?
Yes, the LP2985AIM5-2.8 is pin-compatible with many standard SOT-23-5 LDO regulators offering 150mA at 2.8V. Common alternatives include the MIC5205-2.8 and XC6206P282MR, though you should verify dropout voltage, quiescent current, and enable polarity before substitution.
