TPS730285DBVR Equivalent & Substitute Parts

Part Overview

The TPS730285DBVR is a linear voltage regulator IC from Texas Instruments designed for positive fixed 2.85V output at 200mA in SOT-23-5 surface mount packaging. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. Alternative equivalent and substitute parts are necessary to ensure design continuity and long-term supply chain reliability for applications requiring 2.85V regulation with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS730285DBVR is determined by the following critical parameters:

Fixed Output Voltage: 2.85V output is the primary functional requirement. Substitute parts must deliver identical fixed output voltage.

Output Current Capability: Minimum 200mA output current is required. Substitutes with equal or greater current capacity are acceptable.

Package Compatibility: SOT-23-5 (SC-74A) surface mount package is mandatory for PCB layout compatibility.

Input Voltage Range: Maximum input voltage of 5.5V establishes the upper operating limit.

Dropout Voltage: Maximum 0.21V @ 200mA defines efficiency and thermal performance requirements.

Operating Temperature: -40°C to 125°C operating range must be maintained.

Compliance: RoHS3 compliance and EAR99 classification are required for regulatory and export purposes.

Substitutes are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (enhanced or adjusted specifications within acceptable operating parameters).

Parameter Comparison

Engineering Selection Recommendations

TLV743285PDBVR (Texas Instruments): Active product status with 300mA output current capability. Recommended for new designs and long-term supply assurance. Higher quiescent current (60 µA) and slightly elevated dropout voltage (0.29V @ 300mA) are acceptable trade-offs for increased current headroom and active production status.

TPS730285DBVT (Texas Instruments): Parametric equivalent with identical electrical specifications to the main part. Last Time Buy status limits long-term availability. Suitable only for immediate replacement in existing inventory management scenarios.

LDK120M-R (STMicroelectronics): Active product with adjustable output voltage (0.8V to 5.2V). Requires external resistor network configuration to achieve 2.85V fixed output. Recommended only for designs with flexible voltage requirements or when fixed 2.85V output can be externally configured.

MIC5265-2.85YD5-TR (Microchip Technology): Active product with fixed 2.85V output. Output current limited to 150mA, below the 200mA requirement. Suitable only for applications with reduced current demands (≤150mA). TSOT-23-5 package is mechanically compatible with SOT-23-5 footprints. Exceptional quiescent current (2 µA) for ultra-low power applications.

RT9193-2HGB (Richtek USA Inc.): Active product with 300mA output current and fixed 2.85V output. Recommended for applications requiring higher current capacity. MSL rating of 3 (168 Hours) requires moisture control during storage and assembly compared to MSL 1 of other alternatives.

Frequently Asked Questions (FAQ)

Q: Can TLV743285PDBVR directly replace TPS730285DBVR without PCB modifications?

A: Yes. Both devices use SOT-23-5 packaging with identical pinout and electrical interface. The 300mA output current of TLV743285PDBVR exceeds the 200mA requirement, providing design margin. No PCB layout changes are required.

Q: Is MIC5265-2.85YD5-TR suitable for 200mA applications?

A: No. MIC5265-2.85YD5-TR is rated for maximum 150mA output current. Applications requiring 200mA output current must use alternatives with ≥200mA capability: TLV743285PDBVR, TPS730285DBVT, LDK120M-R, or RT9193-2HGB.

Q: What is the difference between SOT-23-5 and TSOT-23-5 packages?

A: TSOT-23-5 is a thin variant of SOT-23-5 with reduced height. Both packages share identical pinout and are mechanically compatible on standard SOT-23-5 PCB footprints. MIC5265-2.85YD5-TR in TSOT-23-5 packaging is directly substitutable from a footprint perspective.

Q: Why is LDK120M-R listed as a substitute if it requires external configuration?

A: LDK120M-R is included as a manufacturer-recommended alternative for designs requiring adjustable output voltage flexibility. For fixed 2.85V output applications, external resistor divider configuration is necessary. This adds design complexity and is recommended only when voltage adjustability provides system-level benefits.

Q: What is the impact of RT9193-2HGB's MSL 3 rating compared to MSL 1 alternatives?

A: MSL 3 (168 Hours) requires stricter moisture control during storage and assembly compared to MSL 1 (Unlimited). Components must be stored in dry conditions and used within 168 hours of moisture exposure. MSL 1 alternatives (TLV743285PDBVR, TPS730285DBVT, LDK120M-R, MIC5265-2.85YD5-TR) have no moisture sensitivity restrictions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and meet the same regulatory requirements as the main part TPS730285DBVR.

Q: Which substitute offers the best quiescent current performance?

A: MIC5265-2.85YD5-TR provides the lowest quiescent current at 2 µA, compared to 60 µA (TLV743285PDBVR, LDK120M-R), 130 µA (RT9193-2HGB), and 250 µA (TPS730285DBVR, TPS730285DBVT). This advantage is offset by its 150mA maximum output current limitation.
