Overview
The LF25CV is a fixed positive single-output low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It provides a stable 2.5V output with a maximum current capacity of 500mA. The device features a maximum dropout voltage of 700mV and operates within an input voltage range up to 40V absolute maximum. It utilizes a TO-220-3 through-hole package, supporting operation from -40°C to +125°C.
Feature Summary
- Fixed positive linear regulation for stable DC power supply applications
- Integrated inhibit functionality for power management control
- Low dropout characteristic ensuring efficient voltage conversion under varying load conditions
Applications
- General purpose linear voltage regulation in electronic circuits
- Power supply stages requiring fixed 2.5V reference or rail
- Embedded systems utilizing through-hole mounting requirements
Procurement Notes
Verify component authenticity via official STMicroelectronics channels due to obsolete status. Confirm package integrity and pin configuration against the TO-220-3 specification. Cross-reference datasheet revisions to ensure compatibility with existing design constraints. Validate thermal performance parameters for the specific application environment before integration.
Selection Notes
Select this component when a fixed 2.5V output at 500mA is required with through-hole mounting. Consider the 700mV dropout voltage relative to the minimum input voltage. Evaluate thermal dissipation capabilities inherent to the TO-220 package for the expected load current and ambient temperature conditions.
Part Context
Part of the LFxx series of very low drop voltage regulators with inhibit. This series offers fixed output voltages designed for applications requiring stable regulation with minimal quiescent current. The LF25CV specifically targets the 2.5V output segment within this family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative LDOs offering similar 2.5V/500mA specifications and TO-220 packaging if direct replacement is necessary.
