Applications
The TC1186-3.3VCT713 is well suited for powering 3.3 V microcontrollers, sensors, and wireless modules in battery-powered IoT devices and handheld instruments where the small SOT-23-5 footprint minimises board area. Its 0.27 V typical dropout allows operation from a single-cell Li-ion battery down to approximately 3.57 V, extending runtime in portable designs. The shutdown pin also enables low-power sleep modes in energy-harvesting and duty-cycled applications such as environmental sensors and wearable electronics.

Frequently Asked Questions
How low can the input voltage drop before TC1186-3.3VCT713 loses regulation at full 150 mA load?
At 150 mA, the TC1186-3.3VCT713 has a maximum dropout voltage of 0.4 V, so the minimum input voltage for regulation is approximately 3.7 V (3.3 V output plus 0.4 V dropout). With the typical 0.27 V dropout, regulation is maintained down to about 3.57 V input, making it practical for single-cell Li-ion batteries near end-of-discharge.
What is the purpose of the shutdown pin on TC1186-3.3VCT713 and how does it reduce system power?
The active-low shutdown pin places the regulator into a low quiescent-current standby state when asserted, cutting output power to downstream circuits. This enables the host MCU to power-gate sensors, radios, or memory chips that are not needed during sleep cycles, potentially reducing total system current consumption by tens of milliamps, which is critical in battery-operated designs targeting multi-year coin-cell or AA-battery lifetimes.
Why choose TC1186-3.3VCT713 over a similar MCP1700 LDO for a 3.3 V USB-powered design?
Both parts offer low dropout, but the TC1186-3.3VCT713 supplies up to 150 mA versus the MCP1700's 250 mA. For loads under 150 mA, the TC1186-3.3VCT713's SOT-23-5 package provides an active shutdown pin absent on the MCP1700 SOT-23-3, allowing dynamic load switching. If the load regularly exceeds 150 mA, the MCP1700 or a higher-current LDO such as TC1185 at 300 mA would be a better fit.
What output capacitor value is recommended for TC1186-3.3VCT713 to ensure loop stability?
Microchip recommends a minimum 1 µF output capacitor with an ESR between approximately 0.1 Ω and 10 Ω for stable operation. A 1 µF to 10 µF ceramic or tantalum capacitor placed within 5 mm of the output pin is sufficient for most designs. Using very low-ESR ceramic capacitors below 0.01 Ω can reduce phase margin, so a small series resistor of 0.1 Ω to 1 Ω may be added to the capacitor leg if instability is observed.
