Frequently Asked Questions
What is the dropout voltage of the LP2982IM5-3.3?
The LP2982IM5-3.3 has a typical dropout voltage of 120mV and a maximum of 225mV at full 250mA load current. This ultra-low dropout characteristic allows the regulator to maintain a regulated 3.3V output even when the input voltage is only slightly above 3.3V, making it ideal for battery-powered applications where every millivolt counts.
What is the input voltage range and output current rating?
The LP2982IM5-3.3 accepts an input voltage between 4.3V and 16V (absolute maximum 16V) and delivers up to 250mA of continuous output current at a fixed 3.3V. The wide input range makes it compatible with various power sources including unregulated adapters, Li-ion batteries, and USB supplies.
What package does the LP2982IM5-3.3 come in, and is it RoHS compliant?
The LP2982IM5-3.3 is available in a 5-pin SOT-23 (JESD-30 code R-PDSO-G5) surface-mount package, which measures approximately 2.9mm × 1.6mm — a very compact footprint for PCB space-constrained designs. Note that the Pbfree code is listed as 'No', indicating this specific variant uses a tin-lead finish; check with your distributor for RoHS-compliant alternatives if required.
What are typical applications for the LP2982IM5-3.3?
Typical applications include post-regulation for switching converters, microcontroller and DSP supply rails, portable consumer electronics, IoT modules, wireless sensor nodes, and handheld instruments. The low quiescent current and minimal dropout make it especially valuable in battery-operated systems where extending operating time is a priority.
