The MAX6329WHUT-T (Hut Package) is a three-terminal, single-output, adjustable, linear voltage regulator that regulates the output voltage within tolerance of ±1.2%. It is designed for use with low-power, point-of-load regulators when a high degree of accuracy and superior temperature stability is required. The MAX6329WHUT-T is well suited for powering portable stands, cigarette lighters, DC-DC converters, LED lighting, and other low-voltage hardware.

The MAX6329WHUT-T operates in the dropout range of 2.8V to 4V, with an adjustable output voltage range of 1.25V to 13.2V. The adjustable output is set with two external resistors of any value within the range of 100kΩ to 1MΩ. The device supports fast response, precise output voltage accuracy and thermal drift while maintaining the low quiescent current of 2.6 mA max.

The MAX6329WHUT-T offers excellent stability and good overload protection with an overload capability of ±2% over full temperature range and at least 0.3A sink current. This linear regulator has an input/output of 20V, with an operating temperature range of -40°C to +85°C and comes in a compact Hut package, measuring only 2.5mm x 2.5mm. The MAX6329WHUT-T is available in through-hole package.

The MAX6329WHUT-T integrates a voltage reference, pass transistor, and current limit to provide precise output voltage. This device employs a two-stage architecture, consisting of a control loop and a power pass stage, which minimizes the effects of output capacitance, reducing the number of external components required and minimizing cost. During normal operation, the control loop monitors the output voltage and maintains a precise voltage while avoiding the thermal runaway conditions of traditional linear regulators.

The MAX6329WHUT-T provides superior line and load regulation of ±0.2%. This device includes an enable function, which allows it to be powered down to reduce power consumption. As the regulating process does not suffer from the large output voltage swings common in switcher designs, the noise is reduced, which makes it suitable for precision analog designs. Furthermore, no extra components are required for EMI suppression.

The MAX6329WHUT-T integrates a temperature compensation feature which controls the internal temperature coefficient. This allows it to be more accurate when operating in the temperature range of -40C to +85C. The device also has current limiting circuitry which protects against both overloads and output shorts for greater reliability.

The MAX6329WHUT-T can be used to provide a precise voltage in a variety of applications. It is especially useful in portable and battery-powered systems, due to its low quiescent current and small size. The high accuracy and excellent stability of this device make it a suitable choice for powering sensitive analog circuitry, such as precision instrumentation. The MAX6329WHUT-T is a simple and cost-effective solution for providing accurate power.
