TLV1117-25CDCYRG3

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

The TLV1117-25CDCYRG3 is a positive fixed-output low-dropout linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with a maximum continuous output current of 800 mA. The device operates within an input voltage range of 2.7 V to 15 V and features a typical dropout voltage of 1.2 V at full load. It incorporates internal thermal overload protection and current limiting for robust performance. The component is housed in a surface-mount SOT-223-4 package and is rated for operation over an extended temperature range from -40°C to +125°C.

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

Verify the specific suffix 'G3' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free manufacturing specifications. Ensure the ordering part number matches the exact fixed voltage variant required, as the TLV1117 series includes multiple adjustable and fixed options. Confirm that the SOT-223-4 package dimensions align with the target PCB footprint design constraints.

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

Select this component when a fixed 2.5 V rail is required with moderate current demands up to 800 mA. It is appropriate for applications where input voltages vary between 2.7 V and 15 V. Consider the thermal performance in the SOT-223 package if operating near maximum current limits. This regulator offers a balance of cost and performance for standard linear regulation tasks without the complexity of adjustable variants.
