LP38855T-0.8 Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The LP38855T-0.8 is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This device delivers 1.5A output current at a fixed 0.8V output voltage in a TO-220-5 package configuration. The main part is classified as obsolete, which necessitates identification of active equivalent alternatives to ensure design continuity and procurement availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP38855T-0.8 is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 0.8V fixed
• Maximum output current: 1.5A
• Maximum input voltage: 5.5V
• Dropout voltage: 0.180V @ 1.5A
• Package type: TO-220-5 Formed Leads
• Mounting configuration: Through Hole
• Protection features: Over Current, Over Temperature, Short Circuit
• Control features: Enable function

Parts meeting all these specifications are classified as direct equivalents. Variations in product status, packaging format (tube vs. bulk), or compliance certifications do not affect functional substitutability when electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The LP38855T-0.8/NOPB is a direct functional equivalent to the LP38855T-0.8. Both parts share identical electrical specifications, output characteristics, and mechanical packaging. The primary distinction is product status: the original LP38855T-0.8 is obsolete, while the LP38855T-0.8/NOPB maintains active production status.

The LP38855T-0.8/NOPB additionally carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the LP38855T-0.8/NOPB is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can LP38855T-0.8/NOPB replace LP38855T-0.8 in existing designs?

A: Yes. The LP38855T-0.8/NOPB is a direct substitute. All electrical parameters, output specifications, and mechanical package dimensions are identical. Pin configuration and functional behavior remain unchanged.

Q: What is the difference between LP38855T-0.8 and LP38855T-0.8/NOPB?

A: The primary differences are product status and RoHS compliance. The LP38855T-0.8/NOPB is actively produced and carries ROHS3 compliance. The original LP38855T-0.8 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Does packaging format affect substitutability?

A: No. The LP38855T-0.8 and LP38855T-0.8/NOPB are functionally equivalent regardless of packaging format (tube vs. bulk). Both use the same TO-220-5 package with formed leads and through-hole mounting configuration.

Q: Are there any compliance considerations when switching to LP38855T-0.8/NOPB?

A: The LP38855T-0.8/NOPB carries ROHS3 compliance, making it suitable for applications with RoHS regulatory requirements. The original part does not meet RoHS standards. Both maintain identical REACH and ECCN classifications.

Q: What inventory status should be considered for procurement?

A: The LP38855T-0.8 has 827 pieces in stock but is obsolete. The LP38855T-0.8/NOPB has 961 pieces in stock and maintains active production status, making it the preferred choice for ongoing procurement and design continuity.
