The LM4132CQ1MFR2.5 voltage reference is a precision, low-dropout series voltage regulator. It is a three-terminal adjustable voltage reference, with a single-ended output voltage range from 1.25V to 13V and a temperature coefficient of ± 30 ppm/°C (max). The LM4132CQ1MFR2.5 also features a low power consumption of 0.8mW at 30°C, high accuracy of ± 0.33% over the full temperature range, a fast response time, low noise and low output resistance of 0.3Ω. The LM4132CQ1MFR2.5 is ideal for applications such as industrial, telecommunications, automated test equipment, retail, medical, and automotive.

The LM4132CQ1MFR2.5’s main application field is in power supply optimization and as a voltage regulator. It is suitable for voltage reference and voltage regulation tasks in current, voltage and power supply systems. The LM4132CQ1MFR2.5 can be used to replace external voltage references, voltage regulators and voltage shunt regulators in many applications. For example, in power supplies, it can be used to regulate the output voltage to a nominal value, to provide over-voltage, under-voltage and/or reverse polarity protection. It can also be used in a shared current sink or source mode to supply current to a load.

The LM4132CQ1MFR2.5 works on the principle of negative feedback. The voltage reference provides the higher reference voltage to an amplifier and comp features the voltage drop between the reference and the output of the regulator. This feedback loop is used to regulate the output voltage, thus controlling the output current. The output of the LM4132CQ1MFR2.5 is constantly compared to the reference voltage, and if the two voltages become equal, the output voltage is constant. Any input voltage fluctuations are compensated as the output voltage is compared to the reference voltage.

The LM4132CQ1MFR2.5 also features built-in current limiting, over-temperature protection, and an output enable control, allowing the user to enable and disable the output voltage. This makes the LM4132CQ1MFR2.5 ideal for applications requiring a constant voltage output independent of the load, making it suitable for high-side and low-side regulation. The LM4132CQ1MFR2.5 also features adjustable output current limit to maximize power efficiency.
