What are the key features of TPS71202DRCTG4?
- Adjustable dual output with 125 mV typical dropout voltage enables efficient regulation from 2.7 V to 5.5 V input, maximizing usable battery capacity in portable consumer and IoT devices
- Ultra-low 230 mV maximum dropout voltage at full load ensures output regulation is maintained even during input supply droop transients in automotive and industrial systems
- Compact 10-pin SON (small-outline no-lead) package with exposed thermal pad reduces PCB footprint and improves thermal dissipation for space-constrained dual-rail power supply designs
What is TPS71202DRCTG4 used for?
The TPS71202DRCTG4 is used in dual-rail power supply designs for portable consumer electronics, IoT sensor nodes, and wireless communication modules where both analog and digital supply rails must be regulated from a single input ranging from 2.7 V to 5.5 V. Its adjustable output and ultra-low 125 mV dropout allow the device to power microcontrollers, RF transceivers, and memory interfaces simultaneously while maximizing battery runtime down to near-depletion voltage. The SON package's thermal pad also enables adequate heat dissipation in compact enclosures where convection cooling is limited, supporting continuous operation up to the rated output current.

Frequently Asked Questions
What is the dropout voltage of TPS71202DRCTG4 and how does it affect battery life in a 3.3 V system?
The TPS71202DRCTG4 has a typical dropout voltage of 125 mV and a maximum of 230 mV at full output current. For a 3.3 V regulated output, the regulator maintains regulation down to approximately 3.43 V input at the worst-case dropout condition, meaning a Li-ion battery discharging from 4.2 V down to 3.5 V still keeps the output in regulation for the majority of the discharge curve, directly extending battery runtime compared to LDOs with 500 mV or higher dropout.
How should a PCB designer set the output voltage of TPS71202DRCTG4 using external resistors?
The TPS71202DRCTG4 uses a resistor divider network connected to the feedback pin to set the adjustable output voltage. The output voltage is determined by the ratio of two external resistors referenced to the internal reference voltage, allowing any output between the minimum regulated value and the maximum constrained by the 5.5 V input limit. Typical 1% tolerance resistor values in the 100 kΩ range are sufficient to achieve output accuracy within ±2% of the desired setpoint across temperature.
For a dual-rail IoT module requiring 1.8 V and 3.3 V from a 3.7 V Li-ion battery, why is TPS71202DRCTG4 a suitable choice?
The TPS71202DRCTG4 supports 2 adjustable outputs from a single input in the 2.7 V to 5.5 V range, allowing both the 1.8 V digital core and 3.3 V I/O rails to be regulated simultaneously from the 3.7 V nominal Li-ion cell. At 1.8 V output, the 125 mV dropout allows regulation to continue down to approximately 1.93 V input, and at 3.3 V output, regulation persists down to 3.43 V input, covering most of the useful Li-ion discharge range above 3.5 V.
What long-term supply assurance does TPS71202DRCTG4 offer for industrial designs with 10-year production lifetimes?
Texas Instruments assigns the TPS71202DRCTG4 a 15-year YTEOL (Years To End Of Life) rating, guaranteeing production availability through at least 2039 from the product introduction date. This extended longevity commitment reduces redesign risk for industrial automation, medical equipment, and infrastructure products with 10-year or longer service lifetimes. The 10-pin SON package is a mature, widely supported footprint that remains available from multiple assembly houses, further reducing supply chain disruption risk.
