LP5952TL-0.7/NOPB Equivalent & Substitute Parts

Part Overview

The LP5952TL-0.7/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This device delivers 350mA output current in a compact 5-DSBGA package (1.41x1.08mm) with a fixed 0.7V output. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP5952TL-0.7/NOPB is determined by the following critical parameters:

• Fixed output voltage of 0.7V
• Positive output configuration
• Single regulator output
• Output current capability of 350mA or greater
• Maximum input voltage of 4.5V or higher
• Dropout voltage performance compatible with system requirements
• Surface mount packaging with compatible pinout and footprint
• Operating temperature range of -40°C to 85°C or wider
• Equivalent protection features (Over Current, Over Temperature, Under Voltage Lockout)
• RoHS3 compliance and equivalent moisture sensitivity rating

The TCR5AM07,LF from Toshiba Semiconductor and Storage meets these substitution criteria with enhanced specifications in several areas.

Parameter Comparison

Engineering Selection Recommendations

The TCR5AM07,LF is a direct functional substitute for the obsolete LP5952TL-0.7/NOPB. Both devices maintain identical fixed output voltage (0.7V) and operating temperature range (-40°C to 85°C). The substitute provides superior output current capability (500mA versus 350mA), higher maximum input voltage rating (5.5V versus 4.5V), and active product status ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying equivalent environmental and reliability standards. The TCR5AM07,LF operates with slightly elevated quiescent current (55 µA versus 28 µA) and comparable dropout voltage performance (0.21V @ 500mA versus 0.2V @ 350mA).

Package geometry differs between the two devices: the LP5952TL uses 5-DSBGA (1.41x1.08mm) while the TCR5AM07,LF uses 5-DFNB (1.2x1.2mm). PCB layout and footprint modifications are required for implementation. The substitute's smaller package footprint may provide space optimization benefits in constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the TCR5AM07,LF directly replace the LP5952TL-0.7/NOPB without circuit modifications?

A: Functional substitution is possible due to matching output voltage and operating specifications. However, package geometry differs (5-DSBGA versus 5-DFNB), requiring PCB footprint redesign and layout adjustments. Pinout compatibility must be verified against device datasheets before implementation.

Q: What are the key advantages of using TCR5AM07,LF as a substitute?

A: The substitute offers active product status with guaranteed long-term availability, higher output current rating (500mA), increased maximum input voltage (5.5V), and a smaller package footprint (1.2x1.2mm). These characteristics provide design flexibility and supply chain security.

Q: Are there any performance trade-offs when substituting to TCR5AM07,LF?

A: Quiescent current increases from 28 µA to 55 µA. For applications with strict power consumption requirements, this difference may impact battery life or thermal performance. Dropout voltage performance remains comparable across both devices.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the LP5952TL-0.7/NOPB and TCR5AM07,LF are ROHS3 compliant, carry MSL Level 1 ratings, and share identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent regulatory and environmental compliance.

Q: What package considerations are critical for this substitution?

A: The main part uses 5-DSBGA (1.41x1.08mm) while the substitute uses 5-DFNB (1.2x1.2mm). These are different package families requiring separate PCB footprints. Verify pinout alignment and ensure design tools support the new package geometry before layout implementation.

Q: Is the TCR5AM07,LF suitable for applications originally designed for 350mA output?

A: Yes. The substitute's 500mA output capability exceeds the original 350mA requirement, providing adequate current delivery for existing applications. System thermal and power dissipation characteristics should be re-evaluated given the higher current capacity.
