Frequently Asked Questions
What is the output voltage and current rating of TPS72301DBVT?
The TPS72301DBVT provides a fixed 3.3V output voltage with a maximum output current of 50mA. It maintains plus or minus 2% output accuracy over the full operating temperature range of -40C to 125C.
What is the quiescent current of TPS72301DBVT and why does it matter for battery applications?
The TPS72301DBVT has an ultra-low quiescent current of only 450nA, making it ideal for battery-powered applications. This extremely low Iq significantly extends battery life in always-on IoT devices, wearables, and portable electronics where the LDO is continuously powered.
What package is TPS72301DBVT and what are the pin assignments?
TPS72301DBVT is housed in a SOT-23-5 (DBV) 5-pin small outline package. The pins are: IN (input voltage), OUT (regulated output), GND (ground), EN (active-low enable), and NC (no connect). The compact package is suitable for space-constrained PCB designs.
What are suitable replacement or alternative parts for TPS72301DBVT?
Compatible alternatives include the TPS72325DBVT (2.5V variant in same package), XC6206P332MR (Torex, 3.3V/200mA SOT-23-3), and MCP1700T-3302E/TT (Microchip, 3.3V/250mA). For higher current needs, consider the TPS73233DBVR (300mA, same package family).
Is TPS72301DBVT RoHS compliant and what is its operating temperature range?
Yes, TPS72301DBVT is RoHS compliant and lead-free. It operates over the industrial temperature range of -40C to +125C, making it suitable for automotive, industrial, and outdoor applications requiring wide temperature tolerance.
