What are the key features of TPS72118MDBVREP?
- Cap-free output design eliminates external output capacitor, reducing BOM count by 1 component
- Ultra-low 0.15 V dropout voltage at 150 mA enables near-lossless regulation close to battery discharge
- Enhanced Product (EP) qualification ensures extended supply lifecycle for long-horizon industrial and defense programs
What is TPS72118MDBVREP used for?
TPS72118MDBVREP is targeted at battery-powered IoT sensors, portable medical devices, and space-constrained wearables that require a stable 1.8 V rail from a Li-ion or two-cell alkaline source with minimal external components. The cap-free architecture and 150 mA current rating make it straightforward to power low-power MCUs and RF transceivers directly. Its Enhanced Product status suits avionics, industrial control, and defense programs that mandate long component availability windows.

Frequently Asked Questions
What is the dropout voltage of TPS72118MDBVREP at full load and why does it matter for battery life?
The TPS72118MDBVREP maintains regulation with only 0.15 V dropout voltage at 150 mA output, meaning a 1.8 V rail stays in regulation until the battery drops to 1.95 V—extending usable battery runtime compared to conventional LDOs with 0.3 V to 0.5 V dropout under the same load.
Does TPS72118MDBVREP need an output capacitor, and what does that mean for PCB layout?
No output capacitor is required thanks to the cap-free architecture, which removes at least one external 1 µF–10 µF capacitor from the BOM, simplifies PCB routing near the output pin, and reduces total solution area—an important benefit in SOT-23-5 footprint designs measuring roughly 2.9 mm × 1.6 mm.
What does the Enhanced Product (EP) designation mean for procurement of TPS72118MDBVREP?
The Enhanced Product designation commits Texas Instruments to a minimum 10-year availability guarantee and controlled manufacturing changes with advance notice, giving industrial, defense, and avionics program managers confidence in long-term supply continuity without unexpected mid-production obsolescence.
How does TPS72118MDBVREP compare to a standard LDO when powering a 32 MHz MCU from a single Li-ion cell?
With only 0.15 V dropout versus a typical LDO's 0.3 V–0.5 V, TPS72118MDBVREP keeps the 1.8 V output regulated 100–350 mV deeper into battery discharge, adding measurable runtime at 150 mA loads and eliminating the need for a boost stage to compensate for late-cycle voltage sag.
