Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS76927DBVR is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Output voltage configuration (fixed 2.7V output required)
• Output current capability (minimum 100mA)
• Input voltage range (maximum 10V or higher)
• Quiescent current performance
• Protection features (Over Current, Over Temperature)

Mechanical Compatibility Criteria:

• Package type: SOT-23-5 (SC-74A, SOT-753)
• Surface mount mounting type
• Moisture sensitivity level (MSL 1 or equivalent)

Compliance Criteria:

• RoHS3 compliance
• Operating temperature range (-40°C to 125°C)

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications with different packaging or qualification levels) and manufacturer-recommended alternatives (enhanced specifications suitable for the same application space).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements):

TPS76927DBVT and TPS76927QDBVRG4Q1 are parametric equivalents of the TPS76927DBVR, maintaining identical electrical specifications (2.7V fixed output, 100mA current, 28 µA quiescent current, 60dB PSRR). Both are in active product status. The primary differences are packaging format (Tape & Reel versus Cut Tape) and qualification level. TPS76927QDBVRG4Q1 includes automotive-grade qualification (AEC-Q100), suitable for automotive applications requiring enhanced reliability standards.

Manufacturer-Recommended Alternatives:

LDK220M27R (STMicroelectronics) maintains the 2.7V fixed output voltage and SOT-23-5 package but offers doubled output current capability (200mA versus 100mA) and higher maximum input voltage (13.2V versus 10V). Quiescent current is higher at 90 µA. This part is suitable for applications requiring increased current headroom while maintaining the same output voltage specification.

TPS7A2401DBVR (Texas Instruments) is a higher-performance alternative with adjustable output voltage (1.24V to 17.75V), doubled output current (200mA), significantly lower quiescent current (4.5 µA), and superior PSRR (75dB ~ 62dB). Maximum input voltage is 18V. This part requires external resistor network configuration for fixed 2.7V output but provides enhanced performance characteristics and active product status with full manufacturer support.

Selection Basis:

• For direct replacement with minimal design changes: TPS76927DBVT or TPS76927QDBVRG4Q1
• For automotive applications: TPS76927QDBVRG4Q1
• For increased current capacity: LDK220M27R
• For enhanced performance and long-term availability: TPS7A2401DBVR (requires output voltage configuration)

Frequently Asked Questions (FAQ)

Q: Can TPS76927DBVT be used as a direct replacement for TPS76927DBVR?

A: Yes. TPS76927DBVT is a parametric equivalent with identical electrical specifications. The primary difference is packaging format (Tape & Reel versus Cut Tape). Both deliver 2.7V fixed output at 100mA with 28 µA quiescent current. Verify your assembly process accommodates the packaging format.

Q: What is the difference between TPS76927QDBVRG4Q1 and TPS76927DBVR?

A: TPS76927QDBVRG4Q1 is electrically identical to TPS76927DBVR but includes automotive-grade qualification (AEC-Q100) and is supplied in Tape & Reel format. Use this variant for automotive applications or when enhanced reliability documentation is required.

Q: Can LDK220M27R replace TPS76927DBVR in all applications?

A: LDK220M27R is compatible for applications requiring 2.7V fixed output in SOT-23-5 package. It provides doubled output current (200mA) and higher input voltage tolerance (13.2V). However, quiescent current is higher (90 µA versus 28 µA). Verify your application can tolerate increased quiescent current draw.

Q: Is TPS7A2401DBVR a direct replacement?

A: TPS7A2401DBVR is not a direct replacement without design modification. It is an adjustable output regulator requiring external resistor network configuration to set 2.7V output. However, it offers superior performance (4.5 µA quiescent current, 75dB PSRR, 200mA output) and active product status. Use this part if design flexibility permits output voltage configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TPS76927DBVT, TPS76927QDBVRG4Q1, LDK220M27R, TPS7A2401DBVR) are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across -40°C to 125°C, matching the TPS76927DBVR specification.

Q: Can I use TPS7A2401DBVR if I need exactly 2.7V output?

A: Yes. TPS7A2401DBVR can be configured for 2.7V fixed output using external resistor divider network on the feedback pin. Consult the TPS7A2401 datasheet for resistor value calculations. This configuration provides superior performance characteristics compared to the original TPS76927DBVR.
