Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

TLV70736DQNT and TLV70736DQNR (Texas Instruments) represent the closest functional equivalents to the XC6223D3019R-G. Both devices maintain identical input voltage maximum (5.5V), package form factor (4-XDFN Exposed Pad), and control/protection feature sets. The primary difference is output voltage specification (3.6V versus 3V) and output current capacity (200mA versus 300mA). These devices are suitable for applications where the 3.6V output is acceptable and load current does not exceed 200mA. Both variants are RoHS3 compliant with extended operating temperature range (-40°C to 125°C). TLV70736DQNT is supplied in Tape & Reel packaging, while TLV70736DQNR is supplied in Cut Tape format.

Secondary Substitutes (Reduced Current Capacity):

BU30TD2WNVX-TL (Rohm Semiconductor) provides 3V fixed output with 200mA capacity in a 4-UDFN Exposed Pad package. This device maintains the same output voltage as the main part and includes enable control with over-current and over-temperature protection. The package form factor differs slightly (UDFN versus XDFN), requiring PCB layout verification. Input voltage maximum is 6V, providing slightly higher headroom than the main part. Quiescent current is significantly lower (60 µA versus 220 µA), offering improved efficiency in standby conditions.

Specialized Substitute (Low Current Applications):

LD2980ABM30TR (STMicroelectronics) is suitable only for applications requiring 50mA or less output current. This device provides 3V fixed output in a SOT-23-5 package with superior dropout voltage performance (0.225V @ 50mA). The extended input voltage rating (16V maximum) and wider operating temperature range (-40°C to 125°C) provide additional design flexibility for specific applications. This substitute is not recommended for direct replacement in designs requiring 300mA output current.

Compliance and Regulatory Status:

All identified substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the regulatory profile of the XC6223D3019R-G. All devices are classified as active products with current manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can TLV70736DQNT be used as a direct replacement for XC6223D3019R-G?

A: TLV70736DQNT is functionally compatible for applications where output voltage of 3.6V is acceptable and load current does not exceed 200mA. The device maintains identical package form factor (4-XDFN Exposed Pad), input voltage rating (5.5V), and control/protection features. PCB layout and schematic modifications are not required. Applications requiring exactly 3V output or sustained 300mA current should not use this substitute.

Q: What is the difference between TLV70736DQNT and TLV70736DQNR?

A: Both devices are electrically identical Texas Instruments linear regulators with 3.6V output and 200mA capacity. The difference is packaging format: TLV70736DQNT is supplied in Tape & Reel (TR) format for automated assembly, while TLV70736DQNR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on procurement and assembly requirements.

Q: Is BU30TD2WNVX-TL compatible with the XC6223D3019R-G?

A: BU30TD2WNVX-TL is compatible for applications requiring 3V output with maximum 200mA load current. The device uses a 4-UDFN Exposed Pad package instead of 4-XDFN, requiring PCB layout verification for pin spacing and thermal pad dimensions. Enable control and protection features are identical. Input voltage maximum is 6V, providing additional margin. Quiescent current is lower (60 µA), improving efficiency.

Q: Why is LD2980ABM30TR listed as a substitute if it only provides 50mA?

A: LD2980ABM30TR is included for applications where the original design requirement is 50mA or less, or where the 300mA specification is not fully utilized. This device offers superior dropout voltage performance (0.225V @ 50mA) and extended input voltage rating (16V). The SOT-23-5 package is significantly smaller than 4-XDFN, enabling space-constrained designs. This substitute is not appropriate for designs requiring 300mA sustained output current.

Q: What are the key differences in package form factors?

A: The main part uses 4-XDFN Exposed Pad (1x1mm typical). BU30TD2WNVX-TL uses 4-UDFN Exposed Pad with slightly different pin spacing. LD2980ABM30TR uses SC-74A/SOT-753 (SOT-23-5), a larger package with different pin configuration. TLV70736 variants use 4-XDFN Exposed Pad, matching the main part exactly. Package differences require PCB layout verification before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (BU30TD2WNVX-TL, LD2980ABM30TR, TLV70736DQNR, TLV70736DQNT) are RoHS3 compliant and REACH unaffected, matching the regulatory status of XC6223D3019R-G.

Q: What is the significance of the 0.305V dropout voltage specification?

A: Dropout voltage determines the minimum input-to-output voltage differential required for proper regulation. At 300mA output current, XC6223D3019R-G requires 0.305V minimum headroom. Substitute parts with lower dropout voltage (TLV70736 at 0.25V, LD2980 at 0.225V) provide improved efficiency and allow operation with lower input voltages. BU30TD2WNVX-TL has higher dropout (0.46V @ 200mA), requiring greater input voltage margin.

Q: Can output voltage differences affect circuit compatibility?

A: Yes. XC6223D3019R-G provides exactly 3V output. TLV70736 variants provide 3.6V output, a 0.6V difference. This voltage difference may affect circuit operation depending on downstream component specifications. Verify that all powered components tolerate 3.6V before substituting with TLV70736 devices. LD2980ABM30TR and BU30TD2WNVX-TL maintain 3V output, eliminating this concern.

Q: What does PSRR (Power Supply Rejection Ratio) indicate?

A: PSRR measures the regulator's ability to reject input voltage noise and ripple. Higher PSRR values indicate better noise rejection. XC6223D3019R-G provides 80dB @ 1kHz. TLV70736 variants provide 70dB ~ 50dB across 100Hz to 1MHz. BU30TD2WNVX-TL provides 70dB @ 1kHz. LD2980ABM30TR provides 63dB @ 1kHz. Applications with noisy power supplies benefit from higher PSRR specifications.
