Texas Instruments TLV73318PDBVT

Overview

The TLV733P family supplies compact low-voltage rails. The exact TLV73318PDBVT orderable denotes the fixed 1.8 V DBV version in a 250-unit small tape-and-reel carrier. The original catalog package is SC-74A, SOT-753, corresponding to the manufacturer's five-pin SOT-23 DBV outline.

Key Advantages

Feature Summary

• Fixed 1.8 V nominal output with up to 300 mA output-current capability.
• Recommended input range 1.4 V to 5.5 V, subject to regulation headroom and undervoltage-lockout behavior.
• ±1% output accuracy at 25°C and ±1.4% over -40°C to +125°C under the data-sheet electrical test.
• 34 µA typical ground-pin current at zero output load under the stated conditions.
• 0.1 µA typical shutdown current under the manufacturer's EN-low test.
• No output capacitor is required for stability; input and output bypassing can improve transient behavior.

Package & Footprint

The original catalog package is SC-74A, SOT-753. Texas Instruments identifies DBV as a five-pin SOT-23. Check the DBV mechanical drawing and pin-1 orientation for the PCB land pattern.

Layout checks

• Keep the input bypass path short if a capacitor is used.
• Add output capacitance when the transient target calls for it.
• Drive EN to defined valid logic levels.
• Check junction temperature at the actual input and load.

Pin Functions

Texas Instruments TLV733P data sheet SBVS235C gives the DBV five-pin top-view assignment:

Key Specifications

Check the manufacturer voltage- and temperature-specific dropout limits at the intended load, and maintain sufficient input headroom in the actual circuit.

Replacement Considerations

Compare 1.8 V tolerance, input and UVLO behavior, 300 mA rating, EN thresholds, pin order, capacitor needs and package thermal performance before substitution. A five-pin SOT-23 outline alone does not prove compatibility. No internal alternative is linked without an exact production API match.

Manufacturer Information

Texas Instruments TLV733P data sheet SBVS235C (revised July 2019) lists TLV73318PDBVT as a 1.8 V DBV SOT-23 orderable on a 250-unit small tape-and-reel carrier with VCGQ marking.

Applications

Quality & Authenticity

Verify the full TLV73318PDBVT order code, Texas Instruments label, DBV five-pin body, VCGQ marking, reel label and lot traceability. Use current manufacturer package and marking documentation during receiving inspection.

FAQ

Engineering Notice

Use the current Texas Instruments TLV733P data sheet and DBV drawing for final design. Check minimum input voltage, UVLO, output accuracy at load, bypassing, enable logic and junction temperature. Protection functions do not replace normal design margins.
