EZ1085IT

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

The Semtech EZ1085IT is a high-performance positive linear voltage regulator designed for applications requiring low dropout performance at up to 3A output current. It features a maximum dropout voltage of 1.4V and offers fast transient response with ±2% total output regulation over line, load, and temperature conditions. The device includes an adjust pin with a maximum current of 90µA and provides over-current and over-temperature protection. It operates within an industrial temperature range of -40°C to 125°C (TJ) or -40°C to 85°C (TA), depending on specific configuration, and is housed in TO-220 packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Fast transient response with precise output regulation

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

• Applications requiring low dropout performance at high currents
• Industrial equipment power supplies
• General purpose positive voltage regulation

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

Verify the exact operating temperature range specification (TA vs TJ) as sources indicate variations between -40°C to 85°C and -40°C to 125°C. Confirm package type is TO-220. Check availability status as some distributors list it while others may not. Ensure compatibility with required input voltage headroom given the 1.2V to 1.4V dropout characteristics.

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

Select this component when a fixed positive output is needed with high current capability up to 3A. Consider the thermal dissipation requirements due to the TO-220 package and potential power loss across the dropout voltage. Verify that the application does not require adjustable output, as this specific part number typically denotes a fixed voltage variant, unlike the EZ1085ITT which is adjustable.

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

The EZ1085 series consists of high-performance positive voltage regulators from Semtech Corporation. These devices are part of the company's portfolio focused on power management solutions. The IT suffix typically indicates a specific package and temperature rating variation within the broader EZ1085 family, distinguishing it from adjustable versions like the EZ1085ITT.

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

The LM1085IT-12 from Texas Instruments is a similar LDO regulator offering 3A output and comparable dropout characteristics. However, verify if the fixed 12V output of the LM1085IT-12 matches the specific voltage requirement of the EZ1085IT, as the latter's fixed voltage value is not explicitly stated in the provided text.
