Frequently Asked Questions
What are the input and output voltage specifications of the TPS78918DBVTG4?
The TPS78918DBVTG4 operates with an input voltage range of 2.7V to 10V, with an absolute maximum input voltage of 13.5V. It provides a fixed output voltage (the specific output voltage is indicated by the '18' in the part number, corresponding to 1.8V output). The typical dropout voltage is 0.9V, meaning the input must be at least 0.9V higher than the output for proper regulation.
How good is the voltage regulation of the TPS78918DBVTG4?
The TPS78918DBVTG4 offers excellent regulation characteristics with a maximum line regulation of 0.0131% and a maximum load regulation of 0.012%. These figures indicate very stable output voltage performance across varying input voltages and output load currents, making the device suitable for precision analog circuits, RF applications, and sensitive mixed-signal designs where supply noise can degrade system performance.
What package does the TPS78918DBVTG4 use and is it RoHS compliant?
The TPS78918DBVTG4 is housed in a 5-pin SOT23 surface-mount package (JEDEC code R-PDSO-G5), offering a small PCB footprint of approximately 3mm x 1.75mm. The device is RoHS compliant and lead-free with JESD-609 code e4, meeting environmental regulations for hazardous substances. The G4 suffix in the part number also indicates Green compliance, confirming its environmentally responsible construction.
What applications is the TPS78918DBVTG4 best suited for?
The TPS78918DBVTG4 is optimized for ultralow-power, low-noise applications requiring 100mA output current. Typical use cases include powering RF transceivers, precision ADCs and DACs, MEMS sensors, and other noise-sensitive analog circuits in portable and battery-operated devices. Its low dropout voltage of 0.9V and wide input range of 2.7V to 10V make it versatile for single-cell lithium-ion battery applications down to multi-cell battery packs.
