Frequently Asked Questions
What is the minimum input voltage needed to maintain regulation with MCP1700-3002E/TO supplying 250 mA at 3.0 V?
The MCP1700-3002E/TO has a maximum dropout voltage of 350 mV at full 250 mA load, so the input must stay above 3.35 V to maintain the 3.0 V regulated output. For a 4 × AA alkaline pack delivering around 5 V fresh, the regulator handles the full load with over 1.6 V of headroom.
How does the TO-92-3 package of MCP1700-3002E/TO affect assembly options compared to surface-mount LDO variants?
The TO-92-3 is a through-hole package with a 4.5 mm × 4.5 mm body and 1.27 mm lead spacing, suited for wave-solder or hand-soldering in prototypes and low-volume runs. For higher-density SMT production, Microchip offers the MCP1700T-3002E/TT in SOT-23-3, which occupies approximately 2.9 mm × 2.8 mm on the PCB.
For a remote sensor node running from a 4.5 V lithium thionyl chloride primary cell, how long can MCP1700-3002E/TO extend battery life versus a standard LDO?
The MCP1700-3002E/TO draws a very low quiescent current of around 1.6 µA in no-load conditions, which is far below the 50–250 µA quiescent of older LDO families. For a 3600 mAh ER14505 lithium cell powering a sensor sleeping 99% of the time at under 10 µA total, this translates to years of standby life.
Is MCP1700-3002E/TO suitable for designs requiring AEC-Q100 automotive qualification?
The MCP1700-3002E/TO is a commercial and industrial-grade part and is not listed in Microchip's AEC-Q100 automotive-qualified product portfolio. For automotive body-electronics designs operating up to 125°C with AEC-Q100 Grade 1 requirements, engineers should consult Microchip's automotive-qualified LDO selection guide for a compatible alternative.
