LM4041CYM3-ADJ-TR Integrated Circuits (ICs)

The LM4041CYM3-ADJ-TR is a precision, low drop-out (LDO) voltage reference. It is designed for adjustable reference voltage operation when connected to a standard sample and hold circuit. The LM4041CYM3-ADJ-TR is suitable for applications that require a highly accurate, robust, and stable reference voltage, such as in PLCs, end-point converters, power supplies, and instrumentation. This device is capable of providing adjustable output voltages between 1.2V and 12V.

This voltage reference is based on an advanced integrating architecture, which allows the LM4041CYM3-ADJ-TR to offer a high output voltage accuracy up to ±0.5%. The device features internal protection against reverse-voltage and over-voltage conditions, making it suitable for use in situations where the input voltage can vary over a wide range. Additionally, the LM4041CYM3-ADJ-TR\'s low drop-out voltage of 50 mV at full load ensures that output voltages remain unaffected even at very low input voltages. The LM4041CYM3-ADJ-TR also features a very low temperature coefficient of only 1ppm/°C, making it ideal for temperature-sensitive applications.

The LM4041CYM3-ADJ-TR operates in a current-mode configuration and uses an on-chip voltage reference to provide a stable and accurate output voltage at any input voltage. The current mode of operation requires an external loop capacitor to stabilize the regulation loop and provide compensation to ensure good stability at steady-state conditions. The LM4041CYM3-ADJ-TR also includes an internal current-sense amplifier to monitor the output current and limit it to a safe level in the event of an overload. A built-in thermal shutoff protection feature is also included to protect against excessive temperatures.

The LM4041CYM3-ADJ-TR provides a wide range of features to make it suitable for a variety of applications. These features include a quiescent current of 10 µA, an operating temperature range of -40 to +125 °C, a maximum ripple current of 35 mA, and a maximum output voltage of 12 V. The device is housed in an ultra-compact SOT-23 package and is Lead (Pb)-free and RoHS compliant.

In conclusion, the LM4041CYM3-ADJ-TR is a versatile and feature-rich low drop-out voltage reference that is ideal for a wide range of applications. Its highly accurate output voltage and wide operating temperature range make it suitable for temperature-sensitive applications, while its low quiescent current and low drop-out voltage make it suitable for energy-critical applications. Additionally, the device is available in a small SOT-23 package, making it ideal for space-constrained applications.
