Frequently Asked Questions
What is the dropout voltage of the LP2985IM5-3.3/NOPB?
The LP2985IM5-3.3/NOPB has a typical dropout voltage of 280-mV at full 150-mA load, with a maximum of 575-mV. This ultra-low dropout characteristic allows the device to regulate 3.3V output even when the input voltage is as low as approximately 3.6V, making it highly efficient in battery-powered applications.
What input voltage range does the LP2985IM5-3.3/NOPB support?
The LP2985IM5-3.3/NOPB operates with an input voltage range of 4.3V to 16V, with an absolute maximum rating of 16V. This wide input range makes it compatible with a variety of power sources including single-cell Li-ion batteries, 5V USB rails, and 12V industrial supplies.
What are typical applications for the LP2985IM5-3.3/NOPB?
Typical applications include portable consumer electronics, IoT sensor nodes, wearables, RF transceivers, and noise-sensitive analog front-ends. The device's 30-μV RMS output noise and 55-μA quiescent current make it especially suitable for audio circuits, precision ADCs, and battery-operated embedded systems requiring a clean 3.3V rail.
Can the LP2985IM5-3.3/NOPB replace other SOT-23-5 LDO regulators?
Yes, the LP2985IM5-3.3/NOPB is pin-compatible with many SOT-23-5 LDO regulators offering 3.3V fixed output and similar current ratings. When selecting a replacement, verify the input voltage range (4.3V–16V), dropout voltage (280-mV typical), output current capability (150-mA), and quiescent current (55-μA) match your design requirements. Common alternatives include the TLV70033 and MIC5219-3.3.
