Frequently Asked Questions
How does the 150 mV typical dropout voltage of MCP1700T-1802E/TT affect battery life in a coin-cell application?
With only 150 mV typical dropout voltage, the regulator can maintain a regulated 1.8 V output until the battery drains to approximately 1.95 V, extracting significantly more energy from a coin cell or alkaline battery compared to regulators with 300 mV to 500 mV dropout specifications.
Can MCP1700T-1802E/TT supply enough current for a BLE SoC that peaks at 150 mA during radio transmit bursts?
Yes, MCP1700T-1802E/TT is rated for up to 200 mA continuous output current, which covers a 150 mA BLE transmit peak. Designers should add at least 10 µF output capacitance to stabilize the 1.8 V rail during those transmit bursts and prevent voltage droop.
Is MCP1700T-1802E/TT REACH-compliant, and what certifications support its use in European consumer markets?
MCP1700T-1802E/TT carries REACH Compliant and Pb-free codes, satisfying EU REACH regulation requirements and RoHS 2 Directive restrictions. These certifications allow the part to be placed on the European market without additional chemical substance exemption filings.
What is the typical procurement lead time for MCP1700T-1802E/TT, and how volatile is stock availability?
Factory lead time is approximately 5 weeks, which is moderate for an LDO regulator in the SOT-23-3 package. Buyers running production volumes should maintain 6 to 8 weeks of buffer stock given the 5-week replenishment cycle to avoid supply interruptions in high-mix consumer electronics builds.
