Applications
The TC1107-3.3VOA is widely used to supply 3.3 V logic rails from 5 V USB or adapter inputs in embedded systems, wireless modules, and handheld test equipment. Its low dropout characteristic makes it an efficient choice when input-to-output headroom is limited, such as in compact industrial controllers powered from regulated 4.5 V to 5 V rail sources.

Frequently Asked Questions
What is the dropout voltage of the TC1107-3.3VOA, and how does it affect minimum input voltage requirements?
The TC1107-3.3VOA has a nominal dropout voltage of 270 mV at rated load, meaning the minimum input voltage for maintaining a regulated 3.3 V output is approximately 3.57 V under full load conditions. The maximum specified dropout is 480 mV, so designers should plan for at least 3.78 V input in worst-case designs.
Can the TC1107-3.3VOA be powered directly from a 5 V USB supply to generate a 3.3 V logic rail?
Yes. The TC1107-3.3VOA accepts input voltages from 4.3 V to 6 V, so a 5 V USB bus supply is well within its operating range. The 1.7 V headroom available from 5 V down to 3.3 V is far greater than the 270 mV typical dropout, ensuring stable regulation even under full load and tolerance variations.
Does the TC1107-3.3VOA include a shutdown or enable function, and how does it help with power sequencing?
Yes, the TC1107-3.3VOA includes an active-high enable pin. This allows the regulator to be turned off by a supervisory circuit or microcontroller GPIO, enabling controlled power sequencing in multi-rail boards. The enable input requires only a logic-level signal, so no additional drive circuitry is needed when interfacing with 3.3 V or 5 V MCU I/O pins.
Is the TC1107-3.3VOA a long-term stocked item, and what lead time should procurement teams expect?
The TC1107-3.3VOA has a factory lead time of approximately 10 weeks and a YTEOL of 8 years, suggesting it remains in active production for at least several more years. Procurement teams building multi-year products should consider a safety stock equivalent to 3–4 months of consumption to buffer against lead-time spikes common for analog LDO regulators.
