Frequently Asked Questions
What output voltage and maximum current does the LTC1763CS8-3.3#TRPBF deliver?
The LTC1763CS8-3.3#TRPBF delivers a fixed 3.3 V regulated output at up to 500 mA continuous current, making it suitable for powering 3.3 V microcontrollers, RF transceivers, and digital logic in battery-operated portable systems. The fixed output eliminates the need for external resistors that would otherwise set the regulation voltage in adjustable LDO designs.
What is the dropout voltage of LTC1763CS8-3.3#TRPBF at full load and why does this matter for Li-ion battery designs?
At 500 mA output, the LTC1763CS8-3.3#TRPBF maintains a dropout voltage of approximately 300 mV, allowing stable 3.3 V output from input voltages as low as 3.6 V. This low dropout characteristic enables the regulator to keep operating as a Li-ion cell discharges from 4.2 V down toward 3.6 V, maximizing usable battery capacity in portable devices.
How does the 75 uA quiescent current of LTC1763CS8-3.3#TRPBF benefit always-on IoT and wearable applications?
With only 75 uA quiescent current under no-load conditions, the LTC1763CS8-3.3#TRPBF draws minimal standby power in battery-operated IoT sensors and wearable devices during sleep modes. This low quiescent draw extends battery life significantly compared to LDOs with milliamp-level quiescent currents, enabling a 500 mAh coin cell to sustain the regulator for thousands of standby hours.
Which designs call for LTC1763CS8-3.3#TRPBF in its SO-8 package over a smaller LDO package option?
The SO-8 package of the LTC1763CS8-3.3#TRPBF is preferred when up to 500 mA at 3.3 V is needed and PCB area allows moderate component footprint for thermal dissipation. It operates from -40°C to +85°C, suiting commercial-grade portable instruments, industrial sensors, and embedded modules where output current demands exceed the 100 mA to 200 mA limits of ultra-small LDO packages.
