The MAX8840ELT15+T is a high-performance linear voltage regulator designed to regulate a 5V or 3.3V regulated output voltage from an input voltage. It is ideal for mobile applications where long battery life is critical. It is also applicable to applications where space is limited because it is in a very small package.

This voltage regulator includes the on-chip Volgather voltage-sensing technology that eliminates the need for external resistors or capacitors. Its built-in low-power operating mode conserves battery life when the current in the power line drops and the device enters a low-power mode. It also includes an enabling and shutdown circuitry capability providing fast current-transient response.

The MAX8840ELT15+T has a wide input voltage range of 2.3 to 15V and can supply a maximum output current up to 1.5A. It features very low quiescent current of 5 μA at no load or shutdown mode and has excellent temperature stability. The device is resistant to input voltage transients making it suitable for digital variable power supply applications. The thermal shutdown protection circuit prevents the device from damaging in case of excessive power dissipation.

The linear principle of regulating voltage can be simplified as follows. The basic form of the voltage regulator is a transistor or MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) that is placed between the power supply and the load. A feedback loop monitors the output voltage and adjusts the gate voltage of the transistor or MOSFET in order to maintain the output voltage at the desired level. This adjustment is done by an error amplifier that compares the output voltage with a reference voltage and changes the transistor or MOSFET gate voltage accordingly, thus regulating the output voltage to the desired level. Another important part of a linear voltage regulator is the current limiting circuit. This limits the maximum current supplied to the load and prevents it from damaging the circuit in case of short circuits or high-impedance loads.

The MAX8840ELT15+T is suitable for a wide variety of applications, such as mobile phones, digital cameras, personal digital assistants, radio frequency identification devices, and portable medical devices. It is also suitable for use in automotive and industrials because of its low power consumption and small size. Its high input voltage range makes it suitable for a variety of industrial applications. Its ability to provide a regulated output voltage without any external components and its excellent temperature stability make it an ideal choice for portable, low-power applications.
