Electrical Performance Match:

Identical output configuration (Positive, Adjustable)
Matching voltage specifications: 1.25V minimum output, 9V maximum output, 10V maximum input
Equivalent current ratings: 1A output, 55 µA quiescent current, 100 µA maximum supply current
Identical PSRR performance: 55dB at 120Hz
Matching protection features: Over Temperature protection
Identical operating temperature range: -40°C to 125°C

Physical & Compliance Match:

Same mounting type: Surface Mount
Same package designation: SOT-223-5 (TO-261-5, TO-261AB)

Engineering Selection Recommendations

Both LP38692MPX-ADJ/NOPB and LP38692MP-ADJ/NOPB are Active production parts from Texas Instruments with identical electrical specifications and regulatory compliance status. Selection between these parts is determined by supply chain requirements and assembly process compatibility:

LP38692MPX-ADJ/NOPB (Cut Tape & Digi-Reel®): Suitable for applications requiring flexible packaging options or lower volume production runs where cut tape format provides handling advantages.

LP38692MP-ADJ/NOPB (Tape & Reel): Optimized for high-volume automated assembly operations where continuous reel feeding into pick-and-place equipment is standard practice.

Both parts maintain ROHS3 compliance and REACH unaffected status, confirming suitability for regulated markets. The MSL 1 rating (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can LP38692MP-ADJ/NOPB be used as a direct replacement for LP38692MPX-ADJ/NOPB?

A: Yes. Both parts are electrically and functionally identical with matching voltage regulation ranges (1.25V to 9V), output current (1A), and operating temperature specifications (-40°C to 125°C). The difference is packaging format only: Cut Tape & Digi-Reel® versus Tape & Reel.

Q: What is the primary difference between these substitute parts?

A: The supply packaging format differs. LP38692MPX-ADJ/NOPB arrives in Cut Tape and Digi-Reel® format, while LP38692MP-ADJ/NOPB is supplied in continuous Tape & Reel format. The actual components are identical.

Q: Are both parts suitable for automated assembly?

A: Yes. Both SOT-223-5 packaged parts are compatible with surface mount assembly equipment. Tape & Reel format (LP38692MP-ADJ/NOPB) is optimized for continuous automated feeding, while Cut Tape format (LP38692MPX-ADJ/NOPB) offers flexibility for manual or lower-volume automated processes.

Q: Do these parts have identical regulatory compliance?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance differences exist between the two part numbers.

Q: What is the maximum input voltage for these regulators?

A: The maximum input voltage is 10V for both LP38692MPX-ADJ/NOPB and LP38692MP-ADJ/NOPB.

Q: Can the output voltage be adjusted on both parts?

A: Yes. Both parts feature adjustable output voltage regulation with a minimum of 1.25V and maximum of 9V, controlled through external resistor networks.
