NCP1117DT25T5

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

The NCP1117DT25T5G is a fixed-output positive low-dropout linear regulator from onsemi, providing a stable 2.5V output at up to 1A load current. It operates within an input voltage range of 2.9V to 20V and features a typical dropout voltage of 1.2V at full load. The device is housed in a TO-252 (DPAK) surface-mount package with three pins. It supports an operating junction temperature range from -40°C to +125°C and includes internal thermal overload and short-circuit protection circuits for robust performance.

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

Verify the complete part number suffix, typically 'G' for lead-free and RoHS compliance, when ordering. Confirm the specific package variant matches the design requirements. Check official distributor catalogs for current availability status and manufacturing lifecycle information before finalizing procurement plans.

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

Select this component when a reliable 2.5V rail is required for high-current digital loads. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Verify that the thermal management strategy accommodates the power dissipation in the TO-252 package for the intended application environment.

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

This regulator belongs to the NCP1117 family of adjustable and fixed LDOs designed for general-purpose power management. The DT series specifically utilizes the DPAK/TO-252 package, offering higher current handling compared to smaller SOT packages. It serves as a standard solution for converting higher bus voltages to lower logic levels in consumer and industrial electronics.

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

Compatible substitutes include other NCP1117 variants with different fixed outputs or the NCV1117 automotive-grade series. Cross-reference pinouts and thermal characteristics to ensure mechanical and electrical compatibility during replacement.
