AZ1117CH-1.2TRG1

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

The AZ1117CH-1.2TRG1 is a positive fixed-output linear regulator from the AZ1117C series, manufactured by Diodes Incorporated. It provides a fixed output voltage of 1.2V with a maximum continuous output current of 1A. The device features a maximum dropout voltage of 1.3V at 800mA and a typical quiescent current of 6mA. It offers a Power Supply Rejection Ratio (PSRR) of 70dB at 120Hz. The input voltage range supports up to 15V. Integrated protection includes thermal shutdown. The component operates within a junction temperature range of -20°C to 125°C and is housed in a surface-mount SOT-223-3 package.

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

Verify that the specific suffix TRG1 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SOT-223-3 footprint matches the design layout. Ensure compliance with RoHS3 and REACH standards as specified in the manufacturer's environmental statement. Cross-check the part number against official distributor catalogs to avoid confusion with similar variants in the AZ1117 family.

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

Select this component when a precise 1.2V fixed output is required with 1A capability. Consider the 1.3V dropout voltage for minimum input voltage calculations. Evaluate the 6mA quiescent current impact on overall system efficiency. Verify that the SOT-223-3 package thermal performance meets the application's heat dissipation requirements without additional heatsinking.

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

This part belongs to the AZ1117C series of low dropout linear regulators. It shares functional similarities with other fixed-output variants like the 3.3V or 5.0V versions but differs in internal resistor network settings for the 1.2V output. It complements adjustable versions like the ADJ variant, offering a simpler solution for fixed voltage applications.

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

Direct substitutes include other AZ1117CH variants with different fixed voltages if the voltage requirement changes, such as AZ1117CH-3.3TRG1 or AZ1117CH-5.0TRG1. For pin-compatible alternatives with different electrical characteristics, consult the manufacturer's full LDO portfolio for comparable packages and current ratings.
