The MIC2211-WOBML TR is a high-performance, low-dropout (LDO) linear regulator that is designed for high-current, low-dropout voltage regulation in power management systems. The LDO operates from a 4.5V to 7V input voltage range and provides a stable, low-dropout output voltage up to 10V. The MIC2211-WOBML TR is a true voltage regulator, maintaining the output voltage at a fixed level, regulated to ±1.0% accuracy, over a wide temperature range. The output voltage is easily programmed via a simple external resistor divider.

The MIC2211-WOBML TR features a low quiescent current of 100 microamperes, making it ideal for battery-powered applications. The device can output a continuous current of 1.5A and can support up to 2.5A pulsed loads over a 105ms interval. The MIC2211-WOBML TR also features thermal protection, reverse current protection, and current-limit protection.

The MIC2211-WOBML TR is particularly useful for applications such as portable battery-operated devices, telecom systems, and industrial control systems. It is also used as an adjustable reference source or power supply for control and signal processing circuits. The LDO also features improved line and load regulation, higher ripple rejection, and faster start-up time than competing products.

The working principle of the MIC2211-WOBML TR is based on the voltage regulation principle that is common in linear voltage regulators. This involves taking an input voltage and dropping or increasing it to a certain level so that it can act as the output voltage. This is done by controlling the current flow through the regulator, by using a voltage reference voltage, an error amplifier and a set of feedback resistors and capacitors. The error amplifier compares the input and output voltages to calculate the error voltage. This voltage is then used to control the current flow to the output. The output voltage is then regulated and adjusted accordingly. The linear regulator also features over-voltage and over-temperature protection.

The MIC2211-WOBML TR is an efficient and reliable device for voltage regulation in power management systems. Its no-noise operation, low power consumption, and wide operating range make it an ideal choice for applications requiring high-current, low-dropout voltages.
