TPS73215DBVT Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The TPS73215DBVT is a linear voltage regulator IC from Texas Instruments designed for positive fixed 1.5V output at 250mA in a SOT-23-5 surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The device provides essential power management functionality with integrated protection features including over-current, over-temperature, short-circuit, and reverse-polarity protection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS73215DBVT are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage: 1.5V fixed
• Package type: SOT-23-5 surface mount
• Output current capability: minimum 250mA
• Input voltage range: maximum 5.5V or higher
• Operating temperature range: -40°C ~ 125°C
• Control features: Enable function
• Protection features: Over-current and over-temperature protection

Substitution Categories:

Parametric Equivalent: Parts with identical electrical specifications and package type, differing only in packaging format (Tape & Reel vs. Cut Tape).

MFR Recommended Upgrades: Parts with enhanced specifications (higher output current, lower quiescent current, improved PSRR) that maintain full backward compatibility while offering performance improvements.

Cross-Manufacturer Alternatives: Parts from different manufacturers meeting the same electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): TPS73215DBVR is the parametric equivalent to TPS73215DBVT, differing only in packaging format (Cut Tape vs. Tape & Reel). Both parts are obsolete with identical electrical performance and ROHS3 compliance.

For New Designs (Active Product Status): TPS7A2015PDBVR is the manufacturer-recommended upgrade from Texas Instruments. This part is active and offers enhanced specifications including 300mA output current (vs. 250mA), significantly reduced quiescent current (15 µA vs. 550 µA), and improved PSRR (65dB ~ 40dB vs. 58dB ~ 37dB). The slightly higher dropout voltage (0.205V @ 300mA vs. 0.15V @ 250mA) and maximum input voltage (6V vs. 5.5V) provide additional design margin. ROHS3 compliance is maintained through the TPS73215DBVR parametric equivalent.

For Cross-Manufacturer Alternatives: RT9193-15GB from Richtek provides 300mA output current with active product status and ROHS3 compliance. Quiescent current is 130 µA, representing a significant improvement over the original TPS73215DBVT. This part is widely available with 103,400 units in stock.

MIC5305-1.5YD5-TR from Microchip is suitable only for applications requiring 150mA or less output current. This part offers superior PSRR (85dB ~ 65dB) and lower quiescent current (150 µA) but does not meet the 250mA requirement of the original specification.

Compliance Considerations: All recommended substitutes maintain ROHS3 compliance and operate across the -40°C ~ 125°C temperature range. RT9193-15GB has MSL rating of 3 (168 hours), requiring moisture control during storage and handling compared to MSL 1 (unlimited) for other options.

Frequently Asked Questions (FAQ)

Q: Can TPS73215DBVR be used as a direct replacement for TPS73215DBVT? A: Yes. TPS73215DBVR is a parametric equivalent with identical electrical specifications. The only difference is packaging format: TPS73215DBVT is supplied in Tape & Reel format while TPS73215DBVR is supplied in Cut Tape & Digi-Reel® format. Both are obsolete products.

Q: Why is TPS7A2015PDBVR recommended for new designs? A: TPS7A2015PDBVR is an active product from Texas Instruments with enhanced performance characteristics. It provides 300mA output current (vs. 250mA), dramatically reduced quiescent current (15 µA vs. 550 µA for lower power consumption), and improved PSRR. The part maintains the same 1.5V output voltage, SOT-23-5 package, and -40°C ~ 125°C operating range.

Q: What is the difference between SOT-23-5 and TSOT-23-5 packages? A: TSOT-23-5 is a thin variant of the SOT-23-5 package. MIC5305-1.5YD5-TR uses TSOT-23-5 (thin profile), while other substitutes use standard SOT-23-5. Both are mechanically and electrically compatible in most applications, though PCB layout and component height clearance should be verified.

Q: Can MIC5305-1.5YD5-TR replace TPS73215DBVT in all applications? A: MIC5305-1.5YD5-TR is suitable only for applications requiring 150mA or less output current. The original TPS73215DBVT is rated for 250mA, so MIC5305-1.5YD5-TR cannot be used in designs requiring the full 250mA output current specification.

Q: What is the significance of MSL rating differences? A: MSL (Moisture Sensitivity Level) indicates moisture handling requirements during storage and assembly. RT9193-15GB has MSL 3 (168 hours), requiring moisture control and baking procedures before reflow soldering. TPS73215DBVT, TPS73215DBVR, TPS7A2015PDBVR, and MIC5305-1.5YD5-TR all have MSL 1 (unlimited), requiring no special moisture handling.

Q: Are all substitutes ROHS3 compliant? A: TPS73215DBVT, TPS73215DBVR, MIC5305-1.5YD5-TR, and RT9193-15GB are ROHS3 compliant. TPS7A2015PDBVR shows "Not applicable" for RoHS status in the provided data.

Q: What is the inventory status of these parts? A: TPS73215DBVT has 4,100 units in stock. TPS73215DBVR has 6,880 units. TPS7A2015PDBVR has 3,300 units. MIC5305-1.5YD5-TR has 746 units. RT9193-15GB has the highest availability at 103,400 units in stock.
