The MAX1726EUK50+T is a versatile addition to the MaxLinear family of easily configurable linear voltage regulators. It is a low-noise, low-dropout, voltage regulator, designed for use in a variety of applications. This article will discuss the application field, architecture, working principle, and pinouts of the MAX1726EUK50+T.

Application Field

The MAX1726EUK50+T is a combination of two voltage regulators: an shunt-type and an internal bias, both with an adjustable output voltage and an internal positive reference. The internal bias regulator provides an active load current to enable a steady output voltage despite transient or load changes. The combination voltage regulators, along with its low-dropout voltage, low-noise operation, and minimal external components, makes it suitable for demanding and high-performance systems such as automotive, cellular base stations, portable devices, and notebooks.

Architecture and Working Principle

The architecture of the MAX1726EUK50+T is based on a transistor-based linear voltage regulator, whose output voltage is controlled by a proportional-integral (PI) control loop. The voltage is kept constant by controlling the amount of current passing through a pass element, which acts as a variable resistor. The PI control loop is used to adjust the voltage level, based on the difference of the output voltage and the reference voltage.

The MAX1726EUK50+T comes with an internal positive reference and offers a wide range of adjustable output voltages, making it ideal for designing low-noise, low-dropout voltage regulator systems. It uses an input voltage range of 9V to 24V, and its output voltage can be programmed to 0.8V to 4.63V using external resistor dividers. The regulator offers high output accuracy of ±1%, and its low-dropout voltage of up to 0.6V minimizes power loss during operation.

The MAX1726EUK50+T is designed for low-noise operation, with a maximum quiescent current of 10 nA, and maximum noise of 15mV when operating at 1.8V. It also has an integrated soft-start feature for low-noise start-up, and supports current-limit and short-circuit protection, thermal shutdown, and under-voltage lockout (UVLO) features.

Pinouts

The MAX1726EUK50+T has 8 pins, and its pinout is as follows:

• Pin 1: GND - Power Ground.
• Pin 2: IN - Input Power Pin.
• Pin 3: OUT/VADJ - Output Voltage Pin.
• Pin 4: ENABLE - Enable Pin.
• Pin 5: FB - Feedback Voltage Pin.
• Pin 6: RSADJ - External Resistor Divider Pin.
• Pin 7: BYPASS - Bypass Input Pin.
• Pin 8: REF - Reference Voltage Pin.

The GND pin should be connected to a power ground in order to provide a stable reference voltage level. The IN pin is the input power pin. The OUT/VADJ pin is the output voltage pin, and is used to provide the external resistor divider with the required reference voltage. The ENABLE pin is used to control the voltage regulator\'s output voltage. The FB pin is the feedback voltage pin, used for setting the exact output voltage. The RSADJ pin is used for setting the resistor divider. The BYPASS pin is the bypass input pin, used to provide a separate power source to the voltage regulator. Finally, the REF pin is used to set the reference voltage for the voltage regulator.
