Applications
The TPS728285180YZUT is designed for portable electronics and wearable devices requiring a compact, low-dropout 1.8V power supply from a Li-ion battery or 3.3V/5V system rail. Its ultra-low dropout voltage ensures maximum efficiency when the input-output differential is small, ideal for always-on sensor subsystems and wireless connectivity modules. The device is also used in hand-held instruments and IoT edge nodes where board space and quiescent current are constrained.

Frequently Asked Questions
What is the output voltage and maximum output current of the TPS728285180YZUT?
The TPS728285180YZUT provides a fixed 1.8V output voltage with a maximum output current of 200mA. This makes it suitable for powering low-voltage digital logic, microcontroller I/O banks, wireless transceivers, and memory devices in battery-powered portable equipment.
What is the dropout voltage of the TPS728285180YZUT?
The TPS728285180YZUT has a typical dropout voltage of 0.23V and a maximum of 0.4V at full load. This low dropout characteristic allows it to maintain a regulated 1.8V output even when the input supply drops close to the output level, extending battery run time in portable devices.
What package does the TPS728285180YZUT use and what is its input voltage range?
The TPS728285180YZUT is packaged in a 5-ball DSBGA (die-size ball grid array, JESD-30 code R-XBGA-B5), one of the smallest available LDO packages. It accepts input voltages from 2.7V to 6.5V (7V absolute maximum), making it compatible with single-cell Li-ion batteries, USB power, and 5V regulated supplies.
Is the TPS728285180YZUT RoHS compliant and what is its expected product life?
Yes, the TPS728285180YZUT is Pb-free and RoHS compliant (JESD-609 code e1). It has a YTEOL of 15, indicating the product is expected to remain available for an extended period, making it a safe long-term design choice for new product development and volume production.
