Device Overview

Summary

Please consider this device:  MCP1754.   View Side By Side Comparison 
The MCP1801 is a 150 mA, high PSRR, ceramic output capacitor stable Low Dropout (LDO) voltage regulator with shutdown. MCP1801 provides a low noise, highly stable output due to its excellent transient response while consuming only 25 µA of quiescent current. MCP1801's overcurrent limit with current foldback provides excellent short-circuit protection.

For product comparison, please consider: MCP1754

SOT23-5 Voltage Regulator Evaluation Board ( SOT23-5EV-VREG )

The SOT23-5 Voltage Regulator Evaluation Board is designed to provide functional evaluation of Microchip Voltage Regulators that utilize the SOT23-5 package. The SOT23-5 Voltage Regulator Evaluation Board does not come with a voltage regulator soldered onto the board. This allows the user to attach the voltage regulator of their choosing to the board and perform quiescent current, ground current,...
