Frequently Asked Questions
What is the quiescent current of the TPS70628DBVR?
The TPS70628DBVR features an ultra-low quiescent current of just 1 µA, making it ideal for battery-powered applications where standby power consumption is critical. This extremely low IQ extends battery runtime significantly in IoT sensors, wearable devices, and remote monitoring systems operating in sleep or standby modes.
What is the input voltage range and output current capability of the TPS70628DBVR?
The TPS70628DBVR accepts input voltages from 3.8V to 6.5V (absolute maximum 7V) and can deliver up to 150 mA of output current. With a nominal dropout voltage of only 0.245V, it maintains regulation even when the input voltage is close to the output, making it efficient with lithium-ion and alkaline battery supplies.
What package does the TPS70628DBVR use?
The TPS70628DBVR is housed in a SOT-23-5 package (JESD-30 Code: R-PDSO-G5), a compact 5-pin surface-mount package widely used in portable and space-constrained designs. This small footprint makes it easy to integrate into tight PCB layouts for wearable technology, sensor modules, and miniaturized power supply circuits.
Does the TPS70628DBVR have a fixed or adjustable output voltage?
The TPS70628DBVR provides a fixed output voltage (Adjustability: FIXED), meaning the output is set at the factory to a specific voltage level. This eliminates the need for external resistor dividers, simplifying PCB design and reducing component count for applications where a specific regulated voltage is needed.
Is the TPS70628DBVR RoHS compliant?
Yes, the TPS70628DBVR is fully RoHS compliant and lead-free (Pb-free Code: Yes, JESD-609 Code: e4). It meets EU RoHS Directive restrictions on hazardous substances, making it suitable for consumer, industrial, and medical electronics applications that require environmentally responsible component sourcing.
