TPS73130DBVRG4 Equivalent & Substitute Parts

Part Overview

The TPS73130DBVRG4 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3V output at 150mA in SOT-23-5 surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production continuity. The device provides integrated protection features including over-current, over-temperature, short-circuit, and reverse-polarity protection, with an enable control feature for power management applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS73130DBVRG4 are classified based on electrical and mechanical compatibility within the following criteria:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 3V fixed output, 150mA output current, 5.5V maximum input voltage, 0.1V dropout voltage at 150mA, SOT-23-5 packaging, and identical protection features (over-current, over-temperature, short-circuit, reverse-polarity). These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and product status.

Manufacturer Recommended Substitutes provide functional equivalence with allowable variations in specific parameters. The MIC5305-3.0YD5-TR from Microchip Technology maintains 3V output and 150mA current but features different dropout voltage (0.85V @ 150mA), lower quiescent current (150µA vs. 550µA), and higher PSRR performance. The RT9193-30GB from Richtek USA Inc. provides 3V output in SOT-23-5 packaging but with doubled output current capability (300mA) and reduced dropout voltage (0.3V @ 300mA), suitable for applications requiring higher current headroom.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the discontinued TPS73130DBVRG4, the parametric equivalents TPS73130DBVR and TPS73130DBVT are the primary choices. Both maintain identical electrical performance and protection feature sets. TPS73130DBVR is available in Cut Tape and Digi-Reel packaging with 18,768 units in stock, while TPS73130DBVT is supplied in Tape & Reel format with 4,050 units available. Both parts carry Active product status and ROHS3 compliance.

The MIC5305-3.0YD5-TR from Microchip Technology is suitable for applications where lower quiescent current consumption is beneficial. This part reduces standby power draw from 550µA to 150µA and provides superior PSRR performance (85dB ~ 65dB vs. 58dB ~ 37dB). However, the higher dropout voltage (0.85V @ 150mA) may impact performance in low-input-voltage applications. The TSOT-23-5 package is mechanically compatible with SOT-23-5 footprints.

The RT9193-30GB from Richtek USA Inc. offers increased output current capability (300mA vs. 150mA) with improved dropout voltage (0.3V @ 300mA). This part is appropriate for designs requiring current margin or operating at lower input voltages. The MSL rating of 3 (168 hours) requires attention to moisture handling during storage and assembly compared to the MSL 1 rating of other options.

Frequently Asked Questions (FAQ)

Q: Can TPS73130DBVR or TPS73130DBVT be used as direct drop-in replacements for TPS73130DBVRG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, protection features, and SOT-23-5 packaging. The differences are packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Discontinued). PCB layout and schematic connections remain unchanged.

Q: What is the key difference between MIC5305-3.0YD5-TR and the TPS73130 series?

A: The MIC5305-3.0YD5-TR features lower quiescent current (150µA vs. 550µA) and higher PSRR performance, making it suitable for battery-powered or noise-sensitive applications. However, it has higher dropout voltage (0.85V @ 150mA) and omits reverse-polarity protection. The TSOT-23-5 package is mechanically compatible with SOT-23-5 footprints.

Q: When should RT9193-30GB be selected over TPS73130DBVR?

A: The RT9193-30GB is appropriate when the application requires higher output current capability (300mA vs. 150mA) or operates at lower input voltages where the reduced dropout voltage (0.3V @ 300mA) provides design margin. The MSL 3 rating requires controlled moisture exposure during storage and assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original TPS73130DBVRG4.

Q: What packaging considerations apply to the MIC5305-3.0YD5-TR?

A: The MIC5305-3.0YD5-TR uses TSOT-23-5 (thin SOT-23-5) packaging. While mechanically compatible with standard SOT-23-5 footprints, the thinner profile may require verification with PCB assembly equipment and solder reflow profiles.

Q: How does moisture sensitivity level affect part selection?

A: The TPS73130DBVRG4, TPS73130DBVR, TPS73130DBVT, and MIC5305-3.0YD5-TR carry MSL 1 (Unlimited), allowing indefinite shelf storage without moisture baking. The RT9193-30GB carries MSL 3 (168 hours), requiring moisture baking before assembly if storage exceeds 168 hours in standard humidity conditions.
