Frequently Asked Questions
What is the dropout voltage and output current rating of the MIC39101-3.3YMTR?
The MIC39101-3.3YMTR has a maximum dropout voltage of 0.63 V at a 1A output current, allowing it to regulate a stable 3.3 V output from input voltages as low as approximately 3.93 V, which preserves battery runtime in portable and automotive systems.
How does the reversed-battery protection feature help in automotive wiring harness scenarios?
The reversed-battery protection tolerates input polarity inversion up to 16 V, preventing damage to downstream circuits when a battery is connected incorrectly during servicing. This eliminates the need for an external protection diode, saving BOM cost and board space in 12 V automotive designs.
Over what temperature range can the MIC39101-3.3YMTR be used in outdoor industrial equipment?
The regulator operates across a junction temperature range of -40°C to 125°C, making it suitable for outdoor industrial enclosures, engine compartment sensors, and off-road equipment where ambient temperatures frequently exceed standard commercial limits of 0°C to 70°C.
