AZ1117BH-ADJTRE1

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

The AZ1117BH-ADJTRE1 is a positive adjustable linear voltage regulator from Diodes Incorporated, housed in a SOT-223-3 surface-mount package. It delivers an output current of up to 850mA with a typical dropout voltage of 1.2V at that load. The device features an internal bandgap reference ensuring precise output regulation and includes built-in thermal shutdown and current limiting for protection against overload conditions. It operates within a junction temperature range of -40°C to +125°C and supports input voltages up to 15V.

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

Verify the specific suffix 'BH' corresponds to the intended tape-and-reel packaging configuration and ensure the supplier provides official Diodes Incorporated documentation. Confirm that the 850mA rating aligns with your thermal design constraints, as performance may vary based on PCB copper area and ambient temperature conditions.

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

Select this component when a compact SOT-223 footprint is required for adjustable regulation near 1A capacity. Consider the 1.2V dropout characteristic relative to your minimum input-output differential. Ensure adequate thermal dissipation strategies are implemented given the surface-mount package limitations under full load conditions.

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

This part belongs to the AZ1117 series of low-dropout regulators designed for high-current applications. The series offers various fixed and adjustable versions across multiple packages including TO-220, TO-252, and SOT-89. The BH variant specifically denotes the SOT-223 package with adjustable output, targeting space-constrained designs.

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

Direct substitutes include other AZ1117 variants such as AZ1117H-ADJTRE1 or AZ1117D-ADJTRE1 if package compatibility allows. Verify pinout alignment and thermal characteristics before swapping between different package types within the same family.
