Frequently Asked Questions
What makes the TPS73630DBVRG4 a cap-free LDO?
The TPS73630DBVRG4 uses an NMOS pass transistor architecture that is stable without an output capacitor, unlike conventional LDOs requiring 1-10 µF output caps. This simplifies PCB layout, reduces BOM cost, and allows faster transient response in space-constrained portable designs.
What are the input voltage range and output current of the TPS73630DBVRG4?
The TPS73630DBVRG4 accepts an input voltage from 3.2V to 5.5V (absolute max 6V) and delivers up to 400mA continuous output current, with a maximum dropout voltage of 200mV and a typical dropout of only 75mV at full load.
What package does the TPS73630DBVRG4 use and is it RoHS compliant?
The TPS73630DBVRG4 is housed in a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5). It carries JESD-609 code e4, confirming it is lead-free and fully RoHS compliant for use in consumer, industrial, and regulated portable electronics.
What applications is the TPS73630DBVRG4 best suited for?
The TPS73630DBVRG4 is well-suited for portable IoT devices, wearables, handheld instruments, and RF front-end circuits where a stable 3.0V rail is needed with minimal quiescent current. Its cap-free operation and tiny SOT-23 package minimize board area in battery-powered products.
