TLV70229DBVR Equivalent & Substitute Parts

Part Overview

The TLV70229DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 2.9V at 300mA with a maximum dropout voltage of 0.38V at rated current. The device is actively produced and widely stocked (8,782 pcs available), making it suitable for applications requiring low-dropout regulation in compact form factors. Finding equivalent or substitute parts becomes necessary when addressing supply chain constraints, inventory optimization, or design flexibility requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV70229DBVR are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

• Output voltage configuration (fixed positive output)
• Output current capability (300mA minimum)
• Maximum input voltage rating (5.5V)
• Package type (SOT-23-5)
• Surface mount mounting type
• Operating temperature range (-40°C to 125°C)
• Active product status
• RoHS3 compliance

Parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (compatible but with different output voltage ratings).

Parameter Comparison

Engineering Selection Recommendations

TLV70229DBVT (Parametric Equivalent): This part is a direct parametric equivalent to the TLV70229DBVR, sharing identical electrical specifications including output voltage, current rating, dropout voltage, and quiescent current. Both parts are manufactured by Texas Instruments, maintain active product status, and comply with ROHS3 standards. The primary difference is packaging format (Tape & Reel). Selection of this substitute is appropriate when the output voltage of 2.9V is required and inventory of the primary part is constrained.

RT9193-15GB (Manufacturer-Recommended Alternative): This Richtek part is compatible at the mechanical and package level (SOT-23-5, 300mA output, 5.5V maximum input) but delivers a different fixed output voltage of 1.5V. This substitute is suitable only for applications where a 1.5V output voltage is acceptable. The higher quiescent current (130 µA versus 55 µA) and unspecified dropout voltage represent operational differences that must be evaluated against application requirements. This part offers significantly higher inventory availability (103,400 pcs). Selection is appropriate when supply chain priority outweighs the voltage specification difference and the application circuit can accommodate 1.5V output.

Frequently Asked Questions (FAQ)

Q: Can TLV70229DBVT be used as a direct replacement for TLV70229DBVR? A: Yes. Both parts are parametric equivalents with identical electrical specifications. The only difference is packaging format (Tape & Reel). Direct substitution is valid for all applications requiring 2.9V output at 300mA.

Q: Is RT9193-15GB a direct substitute for TLV70229DBVR? A: No. While RT9193-15GB shares the same package type (SOT-23-5) and current rating (300mA), it delivers a fixed output voltage of 1.5V instead of 2.9V. This part is suitable only for applications designed for 1.5V output. Circuit redesign or voltage adjustment may be required.

Q: What are the key parameters that determine substitutability? A: The critical parameters are: fixed output voltage, output current capability (300mA), maximum input voltage (5.5V), SOT-23-5 package type, surface mount configuration, and operating temperature range (-40°C to 125°C). Any deviation in these parameters requires application-level evaluation.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are handling and delivery formats only. They do not affect electrical characteristics or performance. Selection between formats depends on assembly process requirements and inventory management practices.

Q: Are all three parts RoHS3 compliant? A: Yes. TLV70229DBVR, TLV70229DBVT, and RT9193-15GB are all ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: What is the significance of quiescent current differences between TLV70229DBVR and RT9193-15GB? A: The TLV70229DBVR has a quiescent current of 55 µA, while RT9193-15GB draws 130 µA. In battery-powered or low-power applications, this difference affects standby power consumption. The higher quiescent current of RT9193-15GB may be a limiting factor in power-sensitive designs.
