TPS7A0325PDBVR Equivalent & Substitute Parts

Part Overview

The TPS7A0325PDBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a positive fixed 2.5V output at 200mA in a surface-mount SOT-23-5 package. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or specific application requirements within the allowed parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—TPS7A0225PDBVR, TPS7A0525PDBVR, and TPS7A0525PDBVT—are Active products from Texas Instruments with full RoHS3 compliance and REACH unaffected status. Each part maintains the same output voltage (2.5V), output current (200mA), package type (SOT-23-5), and operating temperature range as the primary part.

TPS7A0225PDBVR provides identical electrical performance to the TPS7A0325PDBVR with lower quiescent current (60 nA versus 300 nA) and is available in Cut Tape & Digi-Reel® packaging format. This part is suitable for applications where packaging format flexibility is required.

TPS7A0525PDBVR and TPS7A0525PDBVT both feature reduced maximum input voltage (5.5V versus 6V), lower dropout voltage (0.308V versus 0.36V), and higher quiescent current (3 µA). These parts are functionally equivalent within applications where the lower input voltage specification is acceptable. The TPS7A0525PDBVT differs from TPS7A0525PDBVR only in packaging format designation.

Selection between substitute parts depends on specific application requirements regarding input voltage tolerance, quiescent current performance, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can TPS7A0225PDBVR replace TPS7A0325PDBVR in all applications?

A: Yes. The TPS7A0225PDBVR maintains identical output voltage (2.5V), output current (200mA), maximum input voltage (6V), dropout voltage (0.36V @ 200mA), package type (SOT-23-5), and operating temperature range. The primary difference is lower quiescent current (60 nA versus 300 nA), which provides improved efficiency in low-power standby conditions. The only distinction is packaging format: TPS7A0225PDBVR is supplied in Cut Tape & Digi-Reel® while TPS7A0325PDBVR is supplied in Tape & Reel.

Q: What are the limitations of TPS7A0525PDBVR and TPS7A0525PDBVT as substitutes?

A: Both TPS7A0525 variants have a reduced maximum input voltage specification of 5.5V compared to the 6V rating of TPS7A0325PDBVR. Applications requiring input voltages above 5.5V must use TPS7A0325PDBVR or TPS7A0225PDBVR. The TPS7A0525 variants offer superior dropout voltage performance (0.308V versus 0.36V @ 200mA) and are suitable for applications with input voltage constraints up to 5.5V.

Q: Are TPS7A0525PDBVR and TPS7A0525PDBVT interchangeable?

A: Yes. Both parts are electrically identical with the same output voltage, current, input voltage, dropout voltage, quiescent current, PSRR, protection features, and operating temperature range. The designation difference (PDBVR versus PDBVT) reflects packaging format variation within Tape & Reel supply, not functional differences.

Q: What is the significance of quiescent current differences between these parts?

A: Quiescent current (Iq) represents the regulator's internal current consumption when delivering no load current. TPS7A0225PDBVR (60 nA) and TPS7A0525 variants (3 µA) have lower quiescent current than TPS7A0325PDBVR (300 nA). In battery-powered or low-power standby applications, lower quiescent current reduces overall system power consumption. Selection depends on whether the application prioritizes quiescent current performance or maintains the original TPS7A0325PDBVR specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TPS7A0225PDBVR, TPS7A0525PDBVR, and TPS7A0525PDBVT are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status, matching the compliance profile of TPS7A0325PDBVR.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All parts use identical package type (SC-74A, SOT-753 / SOT-23-5) and surface-mount configuration, allowing direct substitution on existing PCBs without layout modifications. Verify that the application's input voltage requirement does not exceed 5.5V if using TPS7A0525 variants.
