Frequently Asked Questions
What is the minimum input voltage required by the MCP1754T-3302E/OT to maintain a regulated 3.3V output?
The MCP1754T-3302E/OT requires a minimum input voltage of 3.6V, which is only 300 mV above the 3.3V output at typical dropout. This low headroom makes it suitable for single-cell lithium battery systems where the supply rail sags to around 3.5V to 3.6V near end of discharge.
Can the MCP1754T-3302E/OT supply enough current for an MCU and a low-power radio module on a single 3.3V rail?
Yes, the MCP1754T-3302E/OT supports up to 150 mA of continuous output current. A typical combination of a 32-bit MCU at 20 mA and a BLE module at 15 mA peak draw is well within this limit, leaving margin for additional sensors or peripherals on the same regulated 3.3V rail.
How does the SOT-23-5 package help when space is constrained in wearable or compact industrial designs?
The SOT-23-5 package measures approximately 2.9 mm x 1.75 mm with a 0.95 mm pin pitch, one of the smallest 5-pin SMT packages available. In wearable devices or industrial sensor transmitters where board area is at a premium, this footprint allows the LDO to fit alongside the MCU and decoupling capacitors in under 20 mm² of total PCB area.
Is the MCP1754T-3302E/OT compliant with RoHS and REACH requirements for export to EU markets?
Yes, the MCP1754T-3302E/OT carries a JESD-609 e3 designation, confirming it is a lead-free, RoHS-compliant device. Its halogen-free plastic SOT-23-5 package meets EU RoHS Directive 2011/65/EU and REACH SVHC requirements, enabling unrestricted sale and use in European industrial and consumer electronics products.
