Key Features
- 85 mV typical dropout voltage at 50 mA extends battery run time by allowing operation deeper into cell discharge compared to standard LDOs
- Fixed 1.8 V output in a 5-pin SOT-23 package minimizes PCB area in space-constrained portable designs
- 2.8 V to 6.5 V input range covers single-cell Li-ion, USB 5 V, and 3.3 V bus supplies without external boost
Applications
TC1054-1.8VCT713 is ideal for powering 1.8 V microcontrollers, memory chips, and RF transceivers in portable consumer electronics, Bluetooth LE modules, and wearable health monitors. Its ultra-low 85 mV dropout allows the regulator to maintain a clean 1.8 V output even as a lithium-ion cell discharges toward 2.0 V, extracting maximum energy from the battery. The tiny SOT-23-5 footprint also suits space-constrained IoT sensor nodes where multiple LDO rails must coexist on a board smaller than a postage stamp.

Frequently Asked Questions
How does the 85 mV typical dropout voltage of TC1054-1.8VCT713 extend battery life compared to a standard 300 mV dropout LDO?
With 85 mV dropout, TC1054-1.8VCT713 stays in regulation until the battery falls to 1.885 V, while a 300 mV LDO cuts out at 2.1 V. For a 1-cell lithium-ion battery, this translates to extracting an additional 5% to 10% of remaining capacity before the supply rail collapses, measurably extending runtime in always-on wearable or IoT devices.
Can TC1054-1.8VCT713 be powered directly from a USB 5 V bus, and what is the maximum power dissipation in that scenario?
Yes — TC1054-1.8VCT713 accepts up to 6.5 V input, so USB 5 V is within spec. At full 50 mA load with 5 V input and 1.8 V output, the dropout is 3.2 V × 50 mA = 160 mW of internal dissipation. The SOT-23-5 package has a thermal resistance of roughly 250°C/W, so at 160 mW the junction rises about 40°C above ambient — within the rated operating range.
For a Bluetooth LE SoC requiring a stable 1.8 V rail, how does TC1054-1.8VCT713's fixed output configuration simplify design compared to an adjustable LDO?
A fixed 1.8 V output eliminates the 2 external feedback resistors that an adjustable LDO requires, reducing component count by 2 parts and removing the tolerance stack-up error introduced by resistor matching. The TC1054-1.8VCT713's factory-trimmed output accuracy is typically ±1%, ensuring the Bluetooth SoC's RF supply stays within its specified 1.8 V ±5% window without any external tuning.
