LDI92-1.8EN

Overview

The LDI92-1.8EN is a fixed-output linear voltage regulator manufactured by Diotec Semiconductor, designed for surface-mount applications in the SOT-23-5 package. It provides a nominal output voltage of 1.8 V with a maximum output current capability of 500 mA. The device operates within an input voltage range up to 6 V and maintains functionality across an extended junction temperature range from -40 °C to +125 °C. Quiescent current is specified at 800 nA, supporting low-power designs.

Feature Summary

• Fixed positive output voltage regulation
• Ultra-low quiescent current consumption
• Compact SOT-23-5 surface-mount packaging

Applications

• Battery-powered portable electronics
• Low-power sensor interface circuits
• Embedded system power management

Procurement Notes

Verify component authenticity through authorized Diotec Semiconductor distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to integration. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain solderability and long-term reliability during assembly processes.

Selection Notes

Select this regulator when a stable 1.8 V rail is required with minimal standby current draw. The SOT-23-5 footprint suits space-constrained PCB layouts. Verify that the input supply voltage remains within the 6 V maximum limit while ensuring thermal dissipation capabilities match the expected load current and ambient operating conditions.

Part Context

This component belongs to the LDI92 series of low-dropout regulators from Diotec Semiconductor. The series offers various fixed output voltages in the same compact package family, allowing design flexibility for different voltage rails without changing the physical footprint or layout constraints.

Replacement Considerations

Cross-reference with other LDI92-series variants for different voltage outputs. Verify pin compatibility with alternative manufacturers' SOT-23-5 LDOs before substitution.
