PMIC - Voltage Regulators - Linear

The TC2185-5.0VCTTR is a linear voltage regulator from Texas Instruments. It is a single-channel regulator that provides a steady, regulated output voltage for current-limited applications. It is also designed for pulse width modulation (PWM) and pulse frequency modulation (PFM) operations. Its output voltage is adjustable over a wide range, ranging from 2.75 V to 5.25 V.

Application Field and Working Principle

The TC2185-5.0VCTTR is an ideal solution for applications where regulated voltage is needed in order to minimize voltage droop and maintain a constant voltage. Some of its applications field consists of LED lighting, cordless power tool battery packs and other portable device battery packs, communication base stations, and GSM modules. It can also be used in industrial machinery and household appliances.

The working principle of the TC2185-5.0VCTTR is based on the voltage regulator concept. It operates as an adjustable linear voltage regulator and maintains a constant output voltage level even when the input voltages and load currents vary. It has a wide input voltage range (2.75 V to 5.25 V) and a low dropout voltage, making it ideal for low-voltage input applications. As it is an adjustable regulator, the output voltage can be set with external voltage divider resistors.

The TC2185-5.0VCTTR is a linear voltage regulator with low external component count and low quiescent current that helps prolong the operating time of the equipment. It is designed with a power-on reset (POR) output, a short-circuit protection circuit, and a thermal protection circuit that provides high reliability against overvoltage, overcurrent, and overtemperature conditions. The POR circuit ensures that a stable voltage level is achieved at start-up.

The TC2185-5.0VCTTR has excellent current and temperature stability, providing reliable performance and stable output voltage levels over the entire range of operating conditions. It has very good transient response and high PSRR, enabling it to work in the most extreme environmental conditions. The combination of fast transient response and high PSRR helps to maintain a clean, smooth output voltage. Furthermore, the robust design of the TC2185-5.0VCTTR makes it suitable for a wide range of applications, from low current (microamps) to higher currents (up to 1A)

In summary, the TC2185-5.0VCTTR is a linear voltage regulator that is suitable for a wide range of performances in various types of applications. It provides a steady, regulated output voltage over a wide range of operating conditions and is designed with a low dropout voltage and a low quiescent current. It is also designed with protection features to ensure high reliability and stability in extreme environmental conditions.
