AZ1117CD-1.2TRG1

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

The AZ1117CD-1.2TRG1 is a fixed positive linear regulator from the AZ1117C series by Diodes Incorporated. It provides a fixed output voltage of 1.2V with a maximum continuous output current of 1A. The device operates within an input voltage range up to 15V and features a maximum dropout voltage of 1.4V at 800mA. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 70dB at 120Hz and a quiescent current of 6mA. It is housed in a TO-252-3 surface-mount package and supports junction temperatures from -20°C to 125°C.

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

Verify the specific suffix 'CD' corresponds to the required TO-252-3 package and tape-and-reel orientation. Confirm that the 1.2V fixed output aligns with system requirements, as other voltages exist in the AZ1117 family. Ensure compatibility with the specified operating temperature range of -20°C to 125°C for the target application environment.

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

Select this component when a stable 1.2V rail is needed at currents up to 1A with minimal voltage headroom. The TO-252-3 package offers a balance between thermal performance and board space. Consider the 6mA quiescent current for battery life calculations. Verify that the 15V maximum input rating exceeds the highest expected source voltage under all transient conditions.

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

This part belongs to the AZ1117C series of low dropout linear regulators. The series includes various fixed output voltages and adjustable versions across different packages like SOT-223 and TO-220. The AZ1117CD-1.2TRG1 specifically denotes the 1.2V fixed output variant in the TO-252-3 surface-mount package, manufactured by Diodes Incorporated.

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

Direct substitutes within the same manufacturer include other AZ1117CD variants with different fixed output voltages (e.g., AZ1117CD-3.3TRG1) if the voltage requirement changes. Cross-manufacturer equivalents should match the 1A output current, 1.2V output, TO-252-3 package, and similar dropout characteristics.
