AZ1117T-2.85E1

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

The AZ1117T-2.85E1 is a positive fixed linear low-dropout regulator (LDO) manufactured by Diodes Incorporated, part of the AZ1117 series. It provides a fixed output voltage of 2.85V with a maximum continuous output current capability of 1A. The device features a dropout voltage of approximately 1.15V at 1A load and supports an input voltage range up to 15V. It incorporates thermal shutdown protection and operates within a junction temperature range of -40°C to +125°C. The component is housed in a TO-220-3 through-hole package.

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

Verify the specific suffix E1 corresponds to the intended tube packaging configuration as defined by Diodes Incorporated documentation. Confirm that the TO-220-3 through-hole package aligns with your PCB footprint requirements. Ensure the 2.85V fixed output matches the target rail voltage precisely, as adjustable variants require external resistors. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and absolute maximum ratings before finalizing procurement orders.

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

Select this component when a fixed 2.85V rail is required with up to 1A load current in a through-hole form factor. Compare dropout voltage specifications against the minimum input-output differential expected in the application. Consider the thermal performance of the TO-220-3 package relative to the expected power dissipation. Verify that the 15V maximum input rating exceeds the highest possible source voltage under all operating conditions.

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

This device belongs to the AZ1117 family of low-dropout linear regulators from Diodes Incorporated. The series offers various fixed output voltages and adjustable versions across multiple packages including SOT-223, TO-252, and TO-220. The AZ1117T variant specifically denotes the through-hole TO-220-3 package version, distinguishing it from surface-mount counterparts like the AZ1117D or AZ1117CR series.

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

Direct functional substitutes include other 1A LDOs with similar dropout characteristics and TO-220-3 packaging. Verify pinout compatibility (Input, Ground, Output) before substitution. Alternative manufacturers may offer equivalent performance but require validation of thermal resistance and protection feature alignment.
