MCP1824T-2502E/OT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MCP1824T-2502E/OT is a fixed-output Low Dropout (LDO) linear regulator manufactured by Microchip Technology. It provides a regulated output voltage of 2.5 V with a maximum continuous output current capability of 300 mA. The device operates within an input voltage range of 2.1 V to 6.0 V and features a typical dropout voltage of 200 mV at full load. Quiescent current consumption is typically 120 µA, reducing to less than 0.1 µA in shutdown mode. It includes integrated short circuit current limiting and overtemperature protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'E/OT' corresponds to the required temperature grade and tape-and-reel packaging configuration. Confirm that the 2.5 V fixed output variant matches the target circuit design requirements. Ensure compatibility with the SOT-23-5 surface-mount package footprint during PCB layout verification.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.5 V rail is required with up to 300 mA load capacity. It is suitable for applications demanding low quiescent current and fast transient response. Verify that the input voltage remains above 2.1 V and accounts for the dropout voltage under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MCP1824 family of 300 mA CMOS LDO regulators. The MCP1824 series offers both fixed and adjustable output options in various packages. This specific model utilizes the SOT-23-5 package and includes the SHDN and PWRGD pins, distinguishing it from the simpler three-pin MCP1824S variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements include other MCP1824T-xxxxx/OT variants with different fixed output voltages such as MCP1824T-1802E/OT or MCP1824T-3302E/OT. Cross-family alternatives like the MCP1804 series offer similar functionality but with lower current ratings.
