AI Summary

MCP1700 by Microchip Technology: Microchip Technology.

The MCP1702 is an upgraded family member that operates up to 13.2V instead of 6V. It maintains the ultra-low quiescent current profile (2.0 µA vs. 1.6 µA) and provides identical package and pinout options.

  • Direct drop-in replacement from the same manufacturer and product family
  • Significantly higher input voltage rating of 13.2V compared to the original 6.0V
  • Keeps an extremely low quiescent current of 2.0 µA for excellent battery life
  • Slightly higher dropout voltage (625 mV vs 178 mV typical at 250 mA)
  • Slightly higher quiescent current (2.0 µA vs 1.6 µA typical)

The MCP1703 extends the input voltage capability further to 16.0V, making it highly robust against voltage transients. It retains a 2.0 µA quiescent current and identical pin compatibility.

  • Much higher maximum input voltage rating of 16.0V compared to the original 6.0V
  • Low quiescent current of 2.0 µA is ideal for battery-powered devices
  • Same manufacturer and direct physical drop-in option
  • Minimum input voltage is 2.7V (compared to 2.3V for MCP1700), restricting low-voltage inputs
  • Higher dropout voltage of 625 mV typical at 250 mA

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
