TCR2EN19,LF - Voltage Regulators - Linear

The TCR2EN19,LF is a low voltage, low power linear voltage regulator manufactured by STMicroelectronics. It has a maximum output current of 1A and an output voltage range of 1.3V to 18V. The TCR2EN19,LF is a BiCDMOS based LDO (Low Dropout) regulator, which means it has a low dropout voltage and low quiescent current, making it suitable for use in a variety of applications.The TCR2EN19,LF is ideal for applications which require a low-dropout voltage and excellent line and load regulation characteristics. It can be used to provide a stable voltage output for low-power peripherals or communication-enabling circuits. It is also suitable for use in PC cards, LED backlighting, battery-powered applications, such as portable devices, and as an industrial application for temperature/humidity/pressure sensors. In many of these applications, it offers several advantages over other LDO regulators, such as lower quiescent current and higher efficiency.The TCR2EN19,LF features a low dropout voltage of 500mV, adjustable current limits, and a very tight line regulation of 0.2%. The input voltage range is from 3V to 18V, and the output voltage can be adjusted between 1.3V and 18V. The TCR2EN19,LF is protected against short-circuits, over-current and over-temperature.The TCR2EN19,LF has a very good noise rejection ratio of 80 dB, making it suitable for use in noisy environments. The TCR2EN19,LF is a fully monitored device, with a power-on/off switch, power-on reset, output voltage monitor, over-current and reverse-current protection, an adjustable soft start, and hardware shut-down.The TCR2EN19,LF uses an external pass element to regulate the output voltage, usually a metal-oxide semiconductor field effect transistor (MOSFET). This ensures the output voltage is well regulated and reliable. The current passing through the pass element is controlled by the internal error-amplifier circuit. The error amplifier compares the output voltage to a reference voltage, and adjusts the pass element accordingly. The pass element then controls the output voltage.The TCR2EN19,LF has a very good power-to-noise ratio and offers a high level of power efficiency. This makes it suitable for use in battery powered applications, where efficiency and low power consumption is of paramount importance. Overall, the TCR2EN19,LF is an excellent low-power voltage regulator for a variety of applications, including different industrial, consumer, and automotive applications. It is a reliable, safe, efficient and cost-effective solution that is ideal for any application which requires a low-dropout regulator.
