LM78L05IBP Equivalent & Substitute Parts

Part Overview

The LM78L05IBP is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications with 100mA current capacity. This device is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design continuity. The LM78L05IBP operates across a wide input voltage range up to 35V and includes integrated over-temperature and short-circuit protection features suitable for general-purpose power management applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM78L05IBP is determined by strict equivalence across the following electrical and mechanical parameters:

• Output voltage specification: 5V fixed positive output
• Output current capacity: 100mA minimum
• Input voltage tolerance: 35V maximum rating
• Quiescent current: 3mA
• Protection features: Over-temperature and short-circuit protection
• Operating temperature range: -40°C to 85°C
• Mounting configuration: Surface mount technology
• Base product series: LM78L05 family

The LM78L05ITP/NOPB qualifies as a direct substitute based on identical electrical specifications and compatible package classification within the LM78L05 product family.

Parameter Comparison

Engineering Selection Recommendations

The LM78L05ITP/NOPB is the qualified substitute for the obsolete LM78L05IBP. Selection of this substitute is based on the following factors:

• Electrical parameter equivalence across all specified ratings
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance of the substitute part, addressing regulatory requirements for new designs
• Identical functional performance within the LM78L05 product family
• Tape & Reel packaging format suitable for automated assembly processes

The transition from LM78L05IBP to LM78L05ITP/NOPB does not require circuit redesign, as all electrical and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can LM78L05ITP/NOPB be used as a direct replacement for LM78L05IBP in existing designs?

A: Yes. Both parts share identical electrical specifications including 5V fixed output, 100mA current capacity, 35V maximum input voltage, and protection features. The substitute part is functionally equivalent and requires no circuit modifications.

Q: What is the difference between the package designations 8-VFBGA and 8-DSBGA?

A: Both designations refer to 8-pin surface-mount ball grid array packages. The parts are mechanically and electrically compatible for PCB assembly purposes.

Q: Why is the LM78L05IBP listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation. The LM78L05ITP/NOPB remains in active production and serves as the current equivalent for new procurement.

Q: Does the RoHS compliance difference affect substitution?

A: The LM78L05ITP/NOPB is ROHS3 compliant, while the LM78L05IBP is non-compliant. For new designs and applications subject to RoHS regulations, the substitute part is the appropriate selection.

Q: Are there inventory considerations between these parts?

A: The LM78L05IBP has 990 pieces available, while LM78L05ITP/NOPB has 3200 pieces in stock. The substitute part offers greater availability for procurement planning.

Q: What packaging format should be specified for production orders?

A: The LM78L05ITP/NOPB is supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly. Specify this packaging format when placing production orders.
