R1173H001B-T1-FE

Product Overview

The Nisshinbo Micro Devices Inc. R1173H001B-T1-FE is a single-channel linear voltage regulator in a SOT-89-5 surface-mount package. It provides a positive adjustable output from 1 V to 6 V at up to 1 A, with a maximum input voltage of 6 V. The device includes an enable control and protection against over-current and over-temperature conditions. Its 100 µA quiescent current and 70 dB power-supply ripple rejection at 1 kHz support regulated delivery in compact board designs. The specified operating temperature range is -40°C to 85°C.

Key Features

• Positive adjustable linear regulator output with a 1 V to 6 V range.
• Single regulator channel delivering up to 1 A output current.
• Maximum input voltage rating of 6 V.
• Enable control feature for output state management.
• Over-current and over-temperature protection features.
• 100 µA quiescent current.
• 70 dB power-supply ripple rejection at 1 kHz.
• Surface-mount SOT-89-5 package for compact PCB layouts.
• Operating temperature range of -40°C to 85°C.

Applications

• Regulated supply rails for embedded controller and sensor circuits.
• Post-regulation of a 6 V system rail to a lower voltage for peripheral ICs.
• Enable-controlled power domains in modular electronic assemblies.
• Compact linear regulation on boards with limited surface-mount area.

Design & Procurement Notes

Design the output set point within 1 V to 6 V and keep the input at or below 6 V. Account for the 1 A output current, 100 µA quiescent current, and the enable control when planning power sequencing and load behavior. Use the over-current and over-temperature protection as part of a broader system design rather than as a substitute for external safeguards. Choose PCB copper and layout practices suitable for the SOT-89-5 surface-mount package, and verify operation across the -40°C to 85°C range.
