Frequently Asked Questions
What is the maximum output current and input voltage range for MCP1703T-4002E/CB?
MCP1703T-4002E/CB delivers up to 250 mA output current from an input voltage range of 4.725 V to 16 V, making it suitable for a wide variety of portable and industrial supply designs.
How low is the dropout voltage on MCP1703T-4002E/CB and why does that matter for battery-powered circuits?
The MCP1703T-4002E/CB has a nominal dropout voltage of 525 mV and a maximum of 725 mV at full load, allowing 4.0 V regulation from a supply as low as approximately 4.73 V, which extends useful battery runtime before cutoff.
Can MCP1703T-4002E/CB survive the 18 V transients common in automotive 12 V bus environments?
The device is rated with an absolute maximum input voltage of 18 V, so it can handle brief over-voltage transients above the 16 V normal maximum, but continuous operation must stay within the 16 V rated input voltage specification.
When sourcing MCP1703T-4002E/CB in production volumes, what lead time should designers plan for?
Microchip publishes a factory lead time of approximately 6 weeks for MCP1703T-4002E/CB in the SOT-23-3 package, so procurement teams should buffer safety stock accordingly for production runs requiring 250 mA LDO regulators.
