LP2975AIMM-5.0 Equivalent & Substitute Parts

Part Overview

The LP2975AIMM-5.0 is a Linear Regulator Controller IC manufactured by Texas Instruments, designed for positive fixed output voltage regulation with a single output channel. This device operates across a wide input voltage range of 1.8V to 24V and is packaged in an 8-VSSOP surface mount configuration.

The LP2975AIMM-5.0 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing system maintenance, design updates, or production continuity when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2975AIMM-5.0 is determined by the following critical parameters:

• Functional Type: Positive Fixed Linear Regulator Controller
• Output Configuration: Single output channel
• Input Voltage Range: Must accommodate 1.8V to 24V operation
• Supply Current: 180µA specification
• Package Type: Surface mount configuration
• Temperature Range: Operating capability from -40°C to 125°C
• Electrical Compatibility: Matching pin configuration and functional behavior

The identified substitute, LT1575CS8-5#PBF from Analog Devices Inc., shares the core functional classification as a positive fixed linear regulator controller with single output capability. Both devices are surface mount components designed for power management applications.

Parameter Comparison

Engineering Selection Recommendations

The LT1575CS8-5#PBF is an active product from Analog Devices Inc. and carries ROHS3 compliance certification, providing advantages for new designs and systems requiring regulatory adherence. The LP2975AIMM-5.0, being obsolete and RoHS non-compliant, presents sourcing and compliance constraints for ongoing applications.

When evaluating substitution, note that the LT1575CS8-5#PBF operates within a narrower input voltage range (10V ~ 20V versus 1.8V ~ 24V) and a reduced temperature range (0°C ~ 70°C versus -40°C ~ 125°C). Supply current specification differs significantly (12mA versus 180µA). Package formats differ between 8-VSSOP and 8-SO configurations. These differences must be validated against specific application requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the LT1575CS8-5#PBF directly replace the LP2975AIMM-5.0 in existing designs?

A: Direct replacement requires verification of input voltage range compatibility, operating temperature requirements, and package footprint accommodation. The LT1575CS8-5#PBF has narrower input voltage and temperature specifications than the LP2975AIMM-5.0.

Q: What are the package differences between these components?

A: The LP2975AIMM-5.0 uses an 8-VSSOP package (0.118", 3.00mm width), while the LT1575CS8-5#PBF uses an 8-SO package (0.154", 3.90mm width). PCB layout modifications may be necessary for physical accommodation.

Q: Why is the LP2975AIMM-5.0 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates sourcing from existing inventory or identifying functional equivalents for continued system support.

Q: Are there compliance differences between these parts?

A: The LP2975AIMM-5.0 is RoHS non-compliant, while the LT1575CS8-5#PBF is ROHS3 compliant. For applications requiring regulatory compliance, the LT1575CS8-5#PBF is the appropriate selection.

Q: How do supply current specifications affect substitution?

A: The LT1575CS8-5#PBF draws 12mA compared to the LP2975AIMM-5.0's 180µA. This difference impacts power consumption and thermal design considerations in the application circuit.
