TC2186-2.8VCTTR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TC2186-2.8VCTTR is a fixed-output low dropout regulator manufactured by Microchip Technology, providing a regulated 2.8 V output with a maximum load current of 150 mA. It operates within an input voltage range of 2.7 V to 6.0 V and features a typical supply current of 55 µA. The device includes a shutdown mode reducing current to 0.5 µA and an open-drain error flag for out-of-regulation detection. Packaged in a space-saving 5-pin SOT-23A, it supports extended operating temperatures from -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated power-saving shutdown mode that reduces supply current to 0.5 µa maximum when disabled.
• Open-drain error output flag indicates when the regulator output falls out of regulation due to low input voltage or excessive load.
• Built-in overcurrent and thermal protection circuits safeguard against short circuits and overheating conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix CTTR confirms the reel packaging format and standard output voltage setting before procurement. Confirm the component meets AEC-Q100 qualification requirements if automotive grade reliability is necessary for the target application environment. Ensure the ordering quantity aligns with the manufacturer's standard reel size specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring high accuracy and low quiescent current in battery-powered environments. The 150 mA output capability suits moderate load applications where space constraints favor the compact SOT-23A package. Consider the error output functionality if system monitoring for low battery or fault conditions is required.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the TC2054/2055/2186 family of CMOS low dropout regulators designed as upgrades for older bipolar regulators. While sharing similar pinouts and features, the TC2186 specifically provides a higher maximum output current of 150 mA compared to the 50 mA and 100 mA variants in the series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the ERROR output function?

The ERROR pin is an open-drain output that goes low when the output voltage drops below approximately 95% of its nominal value, indicating an out-of-regulation condition.

What is the response time from shutdown mode?

The device typically requires 60 µs to respond and bring the output voltage to 95% of its set value after the shutdown input is released.
