TLV70518PYFPR Equivalent & Substitute Parts

Part Overview

The TLV70518PYFPR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed 1.8V output at 200mA with a maximum dropout voltage of 0.25V, designed for low-power applications requiring stable voltage regulation. The device is Active in product status and widely used in portable electronics, IoT devices, and battery-powered systems where space and power efficiency are critical. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV70518PYFPR are identified based on strict electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

• Fixed output voltage of 1.8V
• Output current rating of 200mA
• Maximum input voltage of 5.5V
• Dropout voltage of 0.25V @ 200mA
• Quiescent current of 55 µA
• PSRR performance of 80dB ~ 55dB (10kHz ~ 1MHz)
• Protection features: Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)
• Enable control feature
• Operating temperature range of -40°C to 125°C
• 4-DSBGA package configuration
• Surface mount mounting type
• ROHS3 compliance and MSL 1 rating

Substitution differences are limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability, which do not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active products from Texas Instruments with identical electrical specifications and functional capabilities. Selection between TLV70518PYFPR and its equivalents should be based on:

Packaging Format Compatibility: TLV70518PYFPR, TLV70518PYFPT, and TLV70518YFPR are supplied in Tape & Reel format, suitable for automated assembly processes. TLV70518YFPT is supplied in Cut Tape & Digi-Reel format, appropriate for lower-volume or manual assembly applications.

Regulatory Compliance: All parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements without moisture sensitivity constraints.

Supply Chain Availability: Inventory levels vary across part numbers. TLV70518PYFPR offers the highest stock availability at 35,400 units, while TLV70518YFPT and TLV70518PYFPT have lower inventory levels. Selection should account for project timeline and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can TLV70518YFPT be used as a direct replacement for TLV70518PYFPR?

A: Yes. TLV70518YFPT is electrically and functionally equivalent to TLV70518PYFPR. The primary difference is packaging format: TLV70518YFPT uses Cut Tape & Digi-Reel packaging, while TLV70518PYFPR uses Tape & Reel. Both are suitable for surface mount assembly on 4-DSBGA packages.

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching electrical parameters: fixed 1.8V output, 200mA output current, 5.5V maximum input voltage, 0.25V dropout voltage, identical protection features, and -40°C to 125°C operating temperature range. All listed substitutes meet these criteria.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects only supply chain logistics and assembly process compatibility, not electrical performance or functional characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—TLV70518PYFPR, TLV70518PYFPT, TLV70518YFPR, and TLV70518YFPT—are ROHS3 compliant with MSL 1 rating, meeting standard environmental and regulatory requirements.

Q: Which part should I select for high-volume production?

A: For high-volume automated assembly, select from TLV70518PYFPR, TLV70518PYFPT, or TLV70518YFPR, all supplied in Tape & Reel format. TLV70518PYFPR offers the highest inventory availability at 35,400 units.

Q: Can these parts be used interchangeably in PCB design?

A: Yes. All substitute parts use the identical 4-DSBGA package configuration and pinout, allowing direct PCB-level interchangeability without design modifications.
