PMIC - Voltage Regulators - Linear

The TLE4266-2GS V33 is a highly integrated three-channel linear voltage regulator with a built-in charge pump. It is ideal for any application requiring high-accuracy and low-noise voltage regulation and on-board voltage conversion. The device provides a regulated output voltage from 2.5V to 6V with a 5V or 12V supply. It also has three analog output channels for pulse width modulation (PWM), current source, and programmable linear regulator (PLR) outputs.

Application Field

The TLE4266-2GS V33 is designed to be used in a wide range of power management applications, including automotive, industrial, and consumer electronic designs. The device is ideal for voltage-regulated power amplifiers and low-noise power supplies for automotive audio systems, digital home appliances, as well as portable and mobile devices.

The TLE4266-2GS V33 also offers a wide operating temperature range from -40°C to 85°C, making it suitable for harsh environmental conditions. The device provides excellent line, load, and temperature regulation, enabling it to operate reliably in rapidly changing ambient conditions. The device is also RoHS compliant and meets the AEC-Q100-qualified standards for automotive applications.

Working Principle

The TLE4266-2GS V33 linear voltage regulator works by controlling the output voltage of its voltage-regulating circuitry. The circuitry maintains a constant output voltage over variations in input and load conditions by modulating the current flow by use of a sensing resistor. The feedback loop monitors the output voltage and adjusts the control current accordingly. This feedback loop ensures accurate and stable output voltage regardless of variations in both input voltage and load current.

The TLE4266-2GS V33 also features adjustable voltage sense threshold (VSENSE) and adjustable load regulation. VSENSE is used to sense the output voltage and to compensate for voltage fluctuations, while load regulation is used to ensure consistent output voltage in the presence of varying load conditions. The voltage adjustment range conservatively varies from 2.5V to 6V, with a minimum load of 1mA.

The device\'s low-noise performance is ensured by its charge pump, which delivers a capacity of up to 5 mugs per channel. The charge pump ensures the voltage regulator delivers ultra-low noise and low-ripple output. The charge pump also helps in maintaining the output voltage level even when the input voltage drops significantly.

The TLE4266-2GS V33 provides a wide range of features, making it suitable for a variety of linear and low-noise power management applications. Its combination of high efficiency, fast transient response, and excellent line and load regulation make it an ideal choice for applications requiring reliable and accurate voltage regulation.
