S-T111B22MC-OGHTFU Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The S-T111B22MC-OGHTFU is an active linear voltage regulator IC manufactured by ABLIC Inc., designed for positive fixed output applications. This device delivers 150mA output current at a fixed 2.2V output voltage with a maximum dropout voltage of 0.35V at 100mA. The regulator features enable control and over-current protection, operating across the industrial temperature range of -40°C to 85°C in a surface-mount SOT-23-5 package.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical parameters including output voltage, output current capacity, dropout voltage characteristics, and package form factor.

Substitute Part Grouping Explanation

Substitution eligibility for the S-T111B22MC-OGHTFU is determined by the following critical parameters:

• Output voltage matching at 2.2V fixed
• Output current capacity of 150mA minimum
• Maximum input voltage of 6V or greater
• Surface-mount package compatibility (SOT-23-5 or SOT-25 footprint variants)
• Operating temperature range of -40°C to 85°C
• Active product status with current manufacturing availability
• ROHS3 compliance and equivalent regulatory certifications

The XC6504A221MR-G from Torex Semiconductor Ltd meets these substitution criteria as a parametric equivalent within the linear voltage regulator category.

Parameter Comparison

Engineering Selection Recommendations

Both the S-T111B22MC-OGHTFU and XC6504A221MR-G maintain active product status with current manufacturing availability and ROHS3 compliance. Both devices are certified as REACH Unaffected and carry EAR99 export classification.

The primary electrical difference between these devices is the dropout voltage characteristic: the S-T111B22MC-OGHTFU exhibits 0.35V dropout at 100mA, while the XC6504A221MR-G exhibits 1.05V dropout at 150mA. This difference affects power dissipation and thermal performance in applications operating near maximum output current.

Package form factors differ between the two parts: the S-T111B22MC-OGHTFU uses SOT-23-5 while the XC6504A221MR-G uses SOT-25. Both are surface-mount packages with compatible pinout arrangements for linear regulator applications, though PCB layout modifications may be required for physical substitution.

Frequently Asked Questions (FAQ)

Q: Can the XC6504A221MR-G directly replace the S-T111B22MC-OGHTFU on existing PCBs?

A: Direct PCB replacement requires verification of package footprint compatibility. The S-T111B22MC-OGHTFU uses SOT-23-5 packaging while the XC6504A221MR-G uses SOT-25 packaging. Both are five-pin surface-mount packages with similar pinout configurations for linear regulator applications, but physical land pattern differences may necessitate PCB layout modifications.

Q: What are the key electrical differences between these two regulators?

A: Both devices deliver 150mA output current at 2.2V fixed output voltage with identical operating temperature ranges and control/protection features. The S-T111B22MC-OGHTFU provides superior dropout voltage performance at 0.35V (100mA), compared to 1.05V (150mA) for the XC6504A221MR-G. The S-T111B22MC-OGHTFU also features lower quiescent current at 1µA versus 1.5µA for the substitute. Maximum input voltage differs at 6.5V versus 6V respectively.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the S-T111B22MC-OGHTFU and XC6504A221MR-G operate across the industrial temperature range of -40°C to 85°C and maintain ROHS3 compliance with equivalent regulatory certifications.

Q: What inventory status applies to these parts?

A: The S-T111B22MC-OGHTFU has 1085 pieces in stock as new original inventory. The XC6504A221MR-G has 1098 pieces in stock as new original inventory, both supplied in Tape & Reel packaging.
