Frequently Asked Questions
Can TC1185-3.0VCT713 regulate from a single-cell Li-ion battery as it discharges from 4.2 V to 3.0 V?
The TC1185-3.0VCT713 requires a minimum input voltage of 4 V and a typical dropout of 270 mV, so it can supply 3.0 V output only when the input stays above 3.27 V. A single Li-ion cell discharges below 4 V before nominal end-of-life, meaning regulation will drop out before the cell is fully depleted — designers should plan for this cutoff around 3.3 V input.
What maximum load current does TC1185-3.0VCT713 support for powering a Bluetooth module on a 3 V rail?
The TC1185-3.0VCT713 is rated for 150 mA continuous output current at 3.0 V ±2.5%. Most Bluetooth Low Energy modules draw 10–50 mA during active radio transmission, so the 150 mA ceiling is adequate for the majority of BLE and Zigbee module supply requirements in battery-powered IoT products.
How does the SOT-23-5 package of TC1185-3.0VCT713 simplify high-volume PCB assembly compared to larger LDO packages?
The SOT-23-5 package has a 2.9 mm × 1.6 mm body with 0.95 mm pin pitch, requiring far less board area than traditional SOT-89 or TO-92 packages. Its small footprint and standard 5-pad SMT land pattern make it compatible with high-speed pick-and-place reflow assembly, reducing production cost per unit at volume.
What output voltage tolerance does TC1185-3.0VCT713 guarantee and how does it affect ADC reference budget in sensor designs?
The TC1185-3.0VCT713 specifies a ±2.5% output voltage tolerance band around 3.0 V, meaning the output can range from 2.925 V to 3.075 V over temperature and load. When used as an MCU supply that also serves as the ADC reference, this 150 mV variation must be included in the total error budget of any ratiometric sensor measurement.
