Frequently Asked Questions
How much output current can TPS79730DCKT supply?
The TPS79730DCKT can supply up to 300mA continuous output current. The fixed 3.0V output maintains ±2% accuracy across the full load range, making it suitable for microcontrollers, sensors, and RF modules in portable designs.
Which package does TPS79730DCKT use and how many pins does it have?
TPS79730DCKT comes in the SC-70-5 (DCK) package with 5 pins. This compact surface-mount package is ideal for space-constrained PCB designs and features an enable pin for controlled power sequencing.
Can TPS79730DCKT operate in industrial temperature environments?
Yes. TPS79730DCKT is rated for -40°C to +125°C, covering both commercial and industrial temperature ranges. This makes it suitable for outdoor IoT devices, automotive accessories, and industrial sensor nodes.
What is the dropout voltage of TPS79730DCKT?
The TPS79730DCKT has a typical dropout voltage of 200mV at 300mA. This means it can regulate to 3.0V even when the input drops to around 3.2V, extending battery life in low-voltage applications.
Which components are compatible replacements for TPS79730DCKT?
Compatible alternatives include the TLV70030DCKR (same TI family, slightly different spec), MCP1703-3002 (Microchip, 250mA 3.0V LDO), and XC6220B301MR (Torex, 700mA 3.0V LDO). Verify dropout, Iq, and enable polarity before substituting.
