TLV1117IDRJR Equivalent & Substitute Parts

Part Overview

The TLV1117IDRJR is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. This device delivers 800mA output current in an 8-SON (4x4) surface mount package and operates across an input voltage range up to 15V with adjustable output from 1.25V to 13.7V. The part is currently in Last Time Buy status, making identification of active equivalent and substitute components essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV1117IDRJR is determined by the following critical parameters:

Primary Substitution Criteria:

• Output configuration (Positive)
• Output type (Adjustable)
• Current output capability (800mA minimum)
• Input voltage range compatibility (15V maximum minimum)
• Output voltage range overlap (1.25V to 13.7V)
• Package type (8-WDFN Exposed Pad)
• Protection features (Over Current, Over Temperature)

Substitute Categories:

Category 1: Direct Pin-Compatible Substitutes (Same Package, Same Current Rating) LM1117LD-ADJ/NOPB, LM1117LDX-ADJ/NOPB, and LM1117ILD-ADJ/NOPB maintain identical 8-WSON (4x4) packaging and 800mA output current specifications. These parts share the same functional pinout and electrical characteristics within acceptable tolerance ranges.

Category 2: Enhanced Performance Substitute (Higher Current Rating) TLV76701DRVR provides increased output current (1A) in a smaller 6-WSON (2x2) package. This part is suitable for applications where the TLV1117IDRJR output current is adequate but a more compact footprint and higher current headroom are beneficial. The higher input voltage rating (16V vs 15V) and lower minimum output voltage (0.8V vs 1.25V) expand application flexibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Same Performance): LM1117ILD-ADJ/NOPB, LM1117LD-ADJ/NOPB, and LM1117LDX-ADJ/NOPB are active products suitable for direct substitution in designs currently using TLV1117IDRJR. All three maintain identical electrical specifications and package footprints. Selection among these three should be based on packaging preference (Cut Tape & Digi-Reel vs. Tape & Reel) and operating temperature requirements. LM1117ILD-ADJ/NOPB supports the full -40°C to 125°C range, while LM1117LD-ADJ/NOPB and LM1117LDX-ADJ/NOPB operate from 0°C to 125°C. All are ROHS3 compliant with established supply availability.

For Enhanced Performance Applications: TLV76701DRVR offers higher output current (1A vs 800mA) and a more compact 6-WSON (2x2) package, making it suitable for space-constrained designs or applications requiring additional current headroom. The lower minimum output voltage (0.8V) and higher input voltage rating (16V) provide expanded design flexibility. This substitution requires PCB layout modification due to package size change. TLV76701DRVR includes Under Voltage Lockout (UVLO) protection, an additional feature not present in the TLV1117IDRJR.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original TLV1117IDRJR. Moisture sensitivity levels vary between MSL 2 and MSL 3; design teams should verify storage and handling procedures align with component specifications.

Frequently Asked Questions (FAQ)

Q: Can LM1117 series parts directly replace TLV1117IDRJR without PCB modifications? A: LM1117ILD-ADJ/NOPB, LM1117LD-ADJ/NOPB, and LM1117LDX-ADJ/NOPB are pin-compatible direct replacements requiring no PCB layout changes. All three share the 8-WDFN Exposed Pad package and identical pinout with TLV1117IDRJR.

Q: What is the key difference between LM1117ILD-ADJ/NOPB and LM1117LD-ADJ/NOPB? A: The primary difference is operating temperature range. LM1117ILD-ADJ/NOPB operates from -40°C to 125°C, while LM1117LD-ADJ/NOPB operates from 0°C to 125°C. Electrical performance and packaging are identical. Packaging format also differs: LM1117ILD-ADJ/NOPB is supplied in Cut Tape & Digi-Reel, while LM1117LD-ADJ/NOPB is supplied in Tape & Reel.

Q: Is TLV76701DRVR a suitable substitute if my application only requires 800mA output? A: TLV76701DRVR is functionally compatible with applications requiring 800mA or less, as it provides 1A output capability. However, substitution requires PCB redesign due to the smaller 6-WSON (2x2) package versus the 8-WSON (4x4) package of TLV1117IDRJR. Use TLV76701DRVR only when the compact footprint and higher current rating provide design benefits.

Q: What are the moisture sensitivity implications for long-term storage? A: TLV1117IDRJR has MSL 2 rating (1 Year shelf life), while LM1117 series substitutes have MSL 3 rating (168 Hours shelf life). MSL 3 components require more stringent moisture control during storage and handling. Verify that component storage facilities meet MSL 3 requirements before committing to LM1117 series parts for inventory.

Q: Are all substitute parts ROHS3 compliant? A: Yes. TLV76701DRVR, LM1117ILD-ADJ/NOPB, LM1117LD-ADJ/NOPB, and LM1117LDX-ADJ/NOPB are all ROHS3 compliant, consistent with TLV1117IDRJR compliance status.

Q: What is the significance of the UVLO protection feature in TLV76701DRVR? A: Under Voltage Lockout (UVLO) protection disables the regulator output when input voltage falls below a specified threshold, preventing unpredictable behavior during low-voltage conditions. TLV1117IDRJR does not include this feature. Applications requiring UVLO functionality benefit from TLV76701DRVR substitution.
