Voltage references are widespread in electronic circuits for providing stable voltage references for absolute precision, low-dropout control, low power applications and complex mixed-signal systems. The LM4041CILPE3, a family of low current, low voltage shunt voltage references from Texas Instruments, offers high accuracy voltage references to meet the requirements of analog-to-digital converters, microprocessors, A/D and D/A converters, precision instrumentation and other sensitive circuitry. The LM4041CILPE3 is designed to operate from a wide supply voltage range and can provide high accuracy and low power consumption in a wide range of applications.

The LM4041CILPE3 is based on the innovative dynamic shunt voltage regulator concept, in which a single small-signal transistor performs a dynamic regulation of the output voltage across an external shunt connected in series with the output node of the device. This technology eliminates the need for external precision resistors and voltage trimming components to maintain a stable output voltage when variations in supply voltage, temperature and loading conditions. The LM4041CILPE3 device maintains high accuracy with temperature drift of less than 0.2 millivolts/°C for temperatures from 0°C to 70°C and stability over long time periods.

The LM4041CILPE3 device is available in a five lead, small-surface-mount package. The LM4041CILPE3 is particularly suited for applications where low quiescent current, low thermal drift and low noise performance are required. The LM4041CILPE3’s low current draw makes it an ideal choice for remote sensing or low voltage applications such as single battery or solar powered devices. The device is also well suited for precision low-dropout voltage regulation.

In addition to its small size and low current draw, the LM4041CILPE3’s other features include low output impedance, fast transient response, protection against reverse battery installation and low external component count. The LM4041CILPE3’s advanced design ensures that the device is capable of achieving reliable operation over temperature and operating conditions. The output voltage is inherently stable and temperature dependent primarily due to the shunt transistor\'s low-temperature-coefficient output characteristics.

The LM4041CILPE3 family also features low-dropout performance due to the dynamic regulation and an output voltage that is accurately regulated over a wide range of input voltage. This allows the output voltage to remain almost constant for variations in input voltage over the entire operating temperature range. The low-dropout performance and the wide operating range provide precision power control in applications such as digital-to-analog converters, microprocessors, memory controllers and other sensitive analog circuits.

The LM4041CILPE3 family includes several variants that offer different voltage output levels, quiescent current and temperature coefficient specifications. The available variants are the BC and CGT versions, both of which offer high accuracy, low temperature coefficient and low noise performance.

The LM4041CILPE3 is especially suitable for precision power supplies, high accuracy A/D-D/A and gain conversion applications, and for single output voltage adjustable voltage regulators. The LM4041CILPE3 is also a suitable choice for space constrained, high-accuracy precision systems such as instrumentation, medical, and military electronics.

In summary, the LM4041CILPE3’s small size and low power consumption make it an ideal choice for space-constrained and high-precision systems. It offers excellent performance with its dynamic shunt voltage regulation, low temperature coefficients, low noise and fast transient response. The device offers precise voltage regulation over a wide range of operating temperatures and provides protection against reverse battery installation.
