Frequently Asked Questions
What is the input voltage range for TPS73033DBVT?
The TPS73033DBVT accepts an input voltage range of 1.7V to 5.5V, making it suitable for single-cell Li-ion batteries and 3.3V or 5V supply rails. The minimum input voltage must exceed the output by the dropout voltage (120mV at 300mA load).
What package does the TPS73033DBVT come in and how many pins does it have?
The TPS73033DBVT comes in a SOT-23-5 (DBV) package with 5 pins. This compact surface-mount package measures approximately 1.6mm x 2.9mm, ideal for space-constrained PCB designs in portable and wearable applications.
What are good alternatives to the TPS73033DBVT?
Compatible alternatives include the TLV733P (same TI family, 300mA LDO), XC6206P332MR (Torex, 200mA), MCP1700T-3302E/TT (Microchip, 250mA), and AP2112K-3.3TRG1 (Diodes Inc, 600mA). Verify pin compatibility and quiescent current specs before substitution.
Is the TPS73033DBVT RoHS compliant and lead-free?
Yes, the TPS73033DBVT is fully RoHS compliant and lead-free (Pb-free). Texas Instruments produces this part under their Green/RoHS program, making it suitable for consumer electronics, industrial, and automotive end-equipment requiring environmental compliance.
What is the minimum order quantity and lead time for TPS73033DBVT?
The TPS73033DBVT is available with a minimum order quantity (MOQ) of 1 unit, with volume pricing available from 10 pieces. Standard market lead time is typically 4-8 weeks for large volumes; spot stock is available for immediate shipment at competitive pricing.
