AZ1117CH-ADJTRG1

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

The AZ1117CH-ADJTRG1 is a low dropout linear regulator from the AZ1117C series, manufactured by Diodes Incorporated. It provides an adjustable output voltage set via two external resistors and supports up to 1A output current. The device operates with an input voltage range of up to 15V and features a typical dropout voltage of 1.2V at 0.8A in the SOT223 package. Key electrical characteristics include a reference voltage of 1.25V (typical), ±1% output voltage accuracy, and a maximum quiescent current of 6mA. It incorporates on-chip thermal shutdown and current limit protection.

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

Verify the specific suffix 'CH' corresponds to the SOT223 package and tape & reel packing format as listed in the ordering information. Confirm that the ADJ designation requires external feedback resistors rather than fixed internal settings. Ensure compliance with RoHS 3 and halogen-free requirements if specified for the target application environment.

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

Select this component when an adjustable voltage rail is required within the AZ1117C family specifications. It is suitable for applications needing transient response optimization and low minimum input voltage operation. Consider the SOT223 package thermal resistance and power dissipation limits relative to the expected load current and ambient temperature conditions.

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

This part belongs to the AZ1117C series of low dropout linear regulators designed for low voltage applications where transient response and minimum input voltage are critical. The series includes fixed output versions (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V) and an adjustable version. The CH suffix indicates the SOT223 package variant.

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

Direct substitutes within the same family include other AZ1117C variants with different packages or fixed voltages, such as AZ1117CR-ADJTRG1 (SOT89) or AZ1117CD-ADJTRG1 (TO252-2). Cross-brand replacements like AMS1117-ADJ exist but require verification of pinout and electrical parameter compatibility.
