Overview
The Diotec Semiconductor LDI1117-2.5U is a positive fixed linear voltage regulator in the LDI1117 series, housed in an SOT-89 package. It provides a nominal output voltage of 2.5V with a maximum input voltage of 15V and delivers up to 1.35A output current. The device features a maximum dropout voltage of 1.25V at 1A, a quiescent current of 10 mA, and includes overcurrent and overtemperature protection.
Feature Summary
- Provides stable regulated power for sensitive electronic circuits
- Integrates thermal and current limiting for operational safety
- Designed for surface-mount assembly on printed circuit boards
Applications
- Battery-powered equipment requiring efficient voltage regulation
- General-purpose power supply sections in consumer electronics
- Post-regulation stages for switching power supplies
Procurement Notes
Verify the specific suffix 'U' corresponds to the SOT-89 package and 15V rating during sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process specifications before finalizing procurement orders.
Selection Notes
Select this component when a 2.5V rail is required with moderate current capacity up to 1.35A. Ensure the input voltage remains within the 15V limit and consider thermal dissipation capabilities given the SOT-89 package size for high-current applications.
Part Context
This part belongs to the LDI1117 family of low-dropout regulators manufactured by Diotec Semiconductor. The 'U' suffix typically denotes the SOT-89 surface-mount package variant, distinguishing it from other package options like SOT-223 found in the same series.
