SP6260EEK-L/TR Linear Voltage Regulator 3V 200mA Equivalent & Substitute Parts

Part Overview

The SP6260EEK-L/TR is a linear voltage regulator IC manufactured by MaxLinear, Inc., designed to deliver a fixed 3V output at 200mA maximum current in a SOT-23-5 surface mount package. This device features an enable control function and over-current protection, operating across the industrial temperature range of -40°C to 85°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the SP6260EEK-L/TR is determined by the following critical parameters:

Fixed output voltage of 3V
Output current capability of 200mA or greater
Input voltage rating of 6V maximum
SOT-23-5 or compatible 5-pin surface mount package
Enable control function
Over-current protection
Operating temperature range of -40°C to 85°C minimum

Substitute parts are grouped into two categories based on output current capacity:

Category 1: 150mA Output Current – Suitable for applications requiring less than 200mA. These parts maintain the 3V fixed output and SOT-23-5 package but deliver reduced current capacity.

Category 2: 200mA Output Current – Direct functional equivalents matching the original 200mA specification. These parts are pin-compatible and electrically equivalent.

Category 3: Higher Current Output (300mA–600mA) – Suitable for designs requiring increased current headroom while maintaining 3V fixed output and compatible packaging. These parts provide design flexibility for future scaling.

Engineering Selection Recommendations

Direct Replacement (200mA Output Current):

BU30TD3WG-TR and BU30SD2MG-MTR from Rohm Semiconductor are the primary direct replacements for the SP6260EEK-L/TR. Both deliver 200mA output current at 3V fixed output with active product status and RoHS3 compliance. BU30SD2MG-MTR offers superior dropout voltage performance (0.15V @ 100mA) and extended operating temperature to 105°C, making it suitable for automotive applications (AEC-Q100 qualified). BU30TD3WG-TR maintains closer electrical characteristics to the original part with 0.46V dropout at 200mA and 70dB PSRR at 1kHz.

Reduced Current Applications (150mA Output Current):

LP3985IM5-3.0/NOPB and LP3985IM5X-3.0/NOPB from Texas Instruments are active alternatives for designs tolerating 150mA maximum output. Both feature superior dropout voltage (0.1V @ 150mA), extended operating temperature to 125°C, and RoHS3 compliance. AP7311-30WG-7 from Diodes Incorporated provides equivalent 150mA capability with additional over-temperature and short-circuit protection. NCP500SN30T1G from onsemi offers ultra-low quiescent current (1 µA) suitable for battery-powered applications.

Increased Current Capacity (300mA–600mA Output Current):

AP7331-30WG-7, AP7335-30WG-7, and AP7365-30WG-7 from Diodes Incorporated provide scalable current options (300mA, 300mA, and 600mA respectively) while maintaining 3V fixed output and active product status. AP7335-30WG-7 offers the lowest dropout voltage (0.2V @ 300mA) among 300mA options. NCP603SN300T1G from Fairchild Semiconductor delivers 300mA output with extended operating temperature to 125°C.

All recommended substitutes maintain RoHS3 compliance and REACH unaffected status. Package compatibility requires verification: SOT-23-5 packages are directly compatible with the original; SOT-25, 5-SSOP, and 5-TSOP packages require PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use a 150mA substitute in place of the 200mA SP6260EEK-L/TR?

A: Only if your circuit draws less than 150mA. The LP3985IM5-3.0/NOPB, LP3985IM5X-3.0/NOPB, AP7311-30WG-7, and NCP500SN30T1G are electrically compatible at 3V fixed output but are current-limited to 150mA. Exceeding this limit causes over-current protection to activate.

Q: What is the difference between BU30TD3WG-TR and BU30SD2MG-MTR?

A: Both deliver 200mA at 3V output. BU30SD2MG-MTR features lower dropout voltage (0.15V @ 100mA vs. 0.46V @ 200mA), higher operating temperature range (-40°C to 105°C vs. -40°C to 85°C), and AEC-Q100 automotive qualification. BU30TD3WG-TR maintains higher PSRR (70dB @ 1kHz) and lower quiescent current (60 µA vs. 80 µA).

Q: Are the Diodes Incorporated AP73xx series pin-compatible with the SP6260EEK-L/TR?

A: No. The AP73xx series uses SOT-25 packaging (5-pin) while the SP6260EEK-L/TR uses SOT-23-5 packaging. Although both are 5-pin surface mount packages, pin assignments differ. PCB layout modification is required.

Q: Which substitute offers the best dropout voltage performance?

A: LP3985IM5-3.0/NOPB and LP3985IM5X-3.0/NOPB from Texas Instruments deliver 0.1V dropout at 150mA. For 200mA operation, BU30SD2MG-MTR provides 0.15V dropout at 100mA. For higher current, AP7335-30WG-7 offers 0.2V dropout at 300mA.

Q: Can I use a higher current substitute (300mA or 600mA) in a design originally specified for 200mA?

A: Yes. Higher current-rated regulators are backward-compatible for lower current applications. AP7331-30WG-7, AP7335-30WG-7, AP7365-30WG-7, and NCP603SN300T1G all maintain 3V fixed output and can replace the SP6260EEK-L/TR in 200mA designs. Package compatibility and PCB layout modification may be required.

Q: What is the difference between SOT-23-5, SOT-25, 5-SSOP, and 5-TSOP packages?

A: These are distinct surface mount package types with different physical dimensions and pin layouts. SOT-23-5 is the original package for SP6260EEK-L/TR. SOT-25, 5-SSOP, and 5-TSOP are not pin-compatible and require PCB redesign. Verify package footprint compatibility before substitution.

Q: Are all recommended substitutes RoHS3 compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute has the lowest quiescent current for battery-powered applications?

A: NCP500SN30T1G from onsemi features 1 µA quiescent current, significantly lower than the original SP6260EEK-L/TR (50 µA) and other substitutes. This makes it ideal for ultra-low-power battery applications, though it is limited to 150mA output current.
