Applications
The TPS7A0233PYCHR is designed for always-on IoT sensor nodes, environmental monitors, and asset trackers where the 25 nA quiescent current directly translates to years of battery life on a coin cell or thin-film battery. Wearable medical devices and smart patches powered by a single-cell Li-ion or energy-harvesting sources in the 1.5 V to 6 V range benefit from its ultra-low standby power and tiny DSBGA footprint. Industrial wireless sensors and GPS tracking modules also use this LDO to maintain a stable 3.3 V rail for a low-power MCU during deep sleep intervals between measurement cycles.

Frequently Asked Questions
How does the 25 nA quiescent current of the TPS7A0233PYCHR extend battery life compared to a standard LDO?
A typical LDO draws 50 µA to 200 µA of quiescent current, which in a coin cell battery-powered IoT node active only 1% of the time would dominate the average current and limit runtime to weeks. The TPS7A0233PYCHR's 25 nA IQ reduces standby current drain by up to 8000× compared to a 200 µA IQ device, extending a 250 mAh CR2032 battery life from months to several years in a sensor node that wakes for 10 ms every 60 seconds.
Can the TPS7A0233PYCHR maintain regulation as a lithium coin cell discharges toward end-of-life voltage?
Yes, the TPS7A0233PYCHR has a typical 205 mV dropout voltage and a maximum of 310 mV at 200 mA load, meaning it continues to regulate at 3.3 V from an input as low as 3.51 V maximum. A CR2032 lithium coin cell discharges to approximately 2.7 V to 3.0 V at end of useful life, well above the minimum 1.5 V input requirement, so the device maintains full regulation throughout the battery's usable discharge curve.
What is the smallest PCB footprint achievable with the TPS7A0233PYCHR, and which form factors benefit?
The 4-pin DSBGA package measures approximately 0.8 mm × 0.8 mm with 0.4 mm bump pitch, requiring a PCB land pattern well under 1 mm², which is the smallest available LDO footprint in this current class. This miniature size directly enables ultra-thin wearable patches, hearing aids, and medical implant power modules where every square millimetre of PCB area is a design constraint.
How does the enable pin on the TPS7A0233PYCHR support multi-stage power sequencing in an IoT design?
The enable input allows a host MCU or power management IC to turn off the 3.3 V LDO rail entirely during deep sleep, reducing total system current to just the 25 nA LDO quiescent draw plus the MCU's own leakage. In a multi-rail IoT module, the LDO can be sequenced on after a main switching regulator has settled, preventing brownout conditions on 3.3 V peripherals such as flash memory or radio transceivers that require a stable supply before initialization.
