TC2185-2.7VCTTR is a low-dropout linear voltage regulator (LDO) with built-in current limiting. It is a low-cost, easy-to-use solution to soften the transition from battery to voltage regulating external supply. This voltage regulator offers high accuracy and is especially suited for low current applications. The TC2185-2.7VCTTR is designed for use with lithium ion and lead acid batteries and provides both continuous and pulse load regulation and low dropout voltage. With its bundled support components, the TC2185-2.7VCTTR is an efficient and reliable voltage regulation solution for portable designs.

Application Field

TC2185-2.7VCTTR voltage regulator has widespread application where gentle startup and/or soft-transition are important as sensitive microcontrollers could damage due to the much higher voltages that are seen when operating battery-powered systems without LDOs. It is typically used in portable and embedded designs, such as medical applications, handsets and handheld systems, smart cards, battery powered systems, gaming and entertainment systems and automotive safety systems. It is also a great choice for automotive and industrial control systems, as well as distributed DC power systems, where low noise, low power consumption and low drop-out voltage are desired.

Working Principle

TC2185-2.7VCTTR is an LDO-style voltage regulator. The LDO is designed to serve as a voltage regulator or current limiter by regulating the difference between the input and output voltages of a circuit. The LDO takes in a higher input voltage than the desired output and then generates a lower output voltage. This process is accomplished through a combination of voltages and/or current. The TC2185-2.7VCTTR also contains current-sensing circuitry to limit output current for a given load.

The TC2185-2.7VCTTR is able to output 2.7V and is typically used with a 160mV dropout voltage. The current-sense feature measures the current flow within the circuit, allowing the TC2185-2.7VCTTR to automatically adjust current flow based on the load. This helps further improves the performance of the circuit by ensuring that the components receive the correct operating current regardless of the load. The TC2185-2.7VCTTR also contains additional features, such as thermal shutdown to protect the circuit from overheating and current limiting to further improve its safety.

In conclusion, the TC2185-2.7VCTTR is a low-cost and easy-to-use low drop-out linear voltage regulator with current-sensing capability. It is ideal for powering sensitive circuits and devices, as well as providing a gentle startup and/or soft-transition in portable and embedded designs in applications such as medical, handsets and handheld systems, gaming, automotive and industrial control systems. The TC2185-2.7VCTTR offers excellent accuracy and performance, enabling designers to reliably protect sensitive circuitry while keeping cost and power consumption down.
