Frequently Asked Questions
What is the dropout voltage of the TC1223-3.0VCT, and how does this affect battery life in a 3.7 V lithium-ion powered design?
The TC1223-3.0VCT has a maximum dropout voltage of 120 mV, meaning it maintains a regulated 3.0 V output as long as the input remains above 3.12 V. In a 3.7 V nominal lithium-ion cell, this allows the regulator to keep operating until the battery discharges to just above 3.1 V, extending usable device runtime compared to LDOs with 300 mV or higher dropout voltages.
What is the maximum input voltage for the TC1223-3.0VCT, and can it accept a 5 V USB supply directly?
The TC1223-3.0VCT accepts a maximum input voltage of 6 V, making it fully compatible with a 5 V USB supply directly at the input pin. This allows the device to power 3.0 V microcontrollers or sensors from USB without an intermediate conversion stage, simplifying BOM and PCB layout for USB-powered IoT and portable equipment.
How does the TC1223-3.0VCT's operating temperature range make it suitable for outdoor industrial sensors?
The TC1223-3.0VCT operates across a junction temperature range of -40°C to +125°C, covering the full extended industrial temperature range. This ensures stable 3.0 V output regulation in outdoor equipment exposed to freezing winters and high summer ambient temperatures, making it a reliable choice for weather stations, pipeline monitors, and field-deployed wireless sensor nodes without requiring thermal management modifications.
