ET5H250S

Overview

The ET5H250S is a linear regulator controller IC featuring a positive fixed output configuration housed in a SOT-223-3 package. It provides a 300mA output current capability with low quiescent current characteristics and includes an enable pin for power management control.

Feature Summary

• Positive fixed output voltage regulation
• Integrated enable function for power control
• Low quiescent current design

Applications

• Portable battery-powered devices
• Embedded systems requiring regulated power rails
• Consumer electronics with space constraints

Procurement Notes

Verify the specific output voltage value associated with the '250' suffix, as datasheets may vary by revision. Confirm thermal requirements for the SOT-223-3 package under maximum load conditions. Ensure compatibility with the target circuit's input voltage range and ground reference before integration.

Selection Notes

Select this component when a fixed output voltage is required alongside low standby consumption. The SOT-223-3 package offers a balance of thermal performance and board space efficiency compared to smaller packages, suitable for moderate current applications up to 300mA.

Part Context

This device belongs to ETEK Microelectronics' portfolio of analog and power management solutions designed for mobile and portable applications. It complements their broader range of LDOs and regulators, focusing on efficiency and compact form factors for modern electronic designs.

Replacement Considerations

Cross-reference with other ETEK models offering similar 300mA fixed outputs in SOT-223-3 packages. Verify pinout compatibility and thermal dissipation capabilities against alternative suppliers' equivalents to ensure seamless substitution without circuit redesign.
