ET5H250F

Overview

The ET5H250F is a linear regulator controller IC manufactured by ETEK Microelectronics. It features a positive fixed output and is housed in an SOT-89 package. The device is characterized as a 300mA Low IQ (Quiescent Current) regulator with an Enable (EN) pin for power management control.

Feature Summary

• Positive fixed output configuration
• Low quiescent current design for efficiency
• Integrated enable control functionality

Applications

• Battery-powered portable electronics
• General purpose voltage regulation circuits
• Embedded systems requiring low standby current

Procurement Notes

Verify the specific datasheet version to confirm exact electrical characteristics, as manufacturer documentation may vary. Ensure the SOT-89 package footprint matches your PCB layout requirements. Confirm that the fixed output voltage meets your system's input specifications before integration.

Selection Notes

Select this component when a fixed positive output is required with minimal static power consumption. The SOT-89 package offers a compact solution for moderate current loads up to 300mA. Consider the enable pin feature if system power sequencing or shutdown capabilities are necessary for the application design.

Part Context

This part belongs to the ETEK Microelectronics linear regulator family, focusing on power management solutions. The manufacturer specializes in analog ICs and power solutions for mobile and embedded applications. The ET5 series typically targets efficiency improvements in battery-operated devices through low quiescent current architectures.

Replacement Considerations

Consult official ETEK Microelectronics documentation for verified substitute part numbers. Cross-referencing should be limited to components with identical pinouts, voltage ratings, and package types to ensure functional compatibility without circuit redesign.
