The MAX8512ETA+ is a monolithic series/shunt linear voltage regulator designed for providing a wide input voltage range with output stability over a wide current range. This device is designed to help system designers to achieve cost, performance, and flexibility in their applications.

The MAX8512ETA+ employs a shunt regulator configuration with series-PTC load control. This enables the device to provide a low output voltage with a wide input voltage range. A unique shunt regulator topology provides a very fast response to changes in input voltage and current enabling the device to meet the demands of input voltage noise and high load transients of today’s mobile systems.

The device provides an adjustable output voltage as low as 0.9V and as high as 4.2V. A wide range of load currents can be accommodated from microamps to 150mA. The MAX8512ETA+ is ideal for battery-driven systems requiring low output voltage and good output voltage regulation over a wide battery voltage range. In addition, this device is ideal for supplying regulators in parallel to a CPU or ASIC to provide power supply flexibility.

The MAX8512ETA+ is designed to operate in a wide temperature range from -40C to 85C, making it suitable for a variety of portable and battery-powered applications. The device is available in 10-pin TDFN, space-saving 3mm × 3mm package. This IC has a low operating current (IQ) of 120µA that helps to reduce power consumption.

The MAX8512ETA+ offers overvoltage protection and provides an adjustable current limiting feature. It also provides thermal shutdown and reverse current protection. This device has a fast transient response, low 0.5Ω internal current sensing resistor, and low dropout voltage. With its low quiescent current and its wide operating temperature range, the MAX8512ETA+ is an excellent choice for battery-operated portable equipment.

The MAX8512ETA+ is designed to reduce output voltage noise and ripple by using a patented, cascode-based, linear regulator topology. This regulator also features a low-power operation mode, in which the switching frequency is decreased and the current consumption is lowered. This feature enables improved efficiency and reduced noise in portable applications.

The MAX8512ETA+ offers a multi-phase output, which helps to reduce output voltage ripple. This regulator features an external loop compensation, which can be adjusted to optimize the device for an application. The external components required by the loop compensation are only capacitors, simplifying the design of the supply.

Overall, the MAX8512ETA+ is an ideal linear voltage regulator for system designers. This regulator provides a wide input voltage range, low output voltage, high accuracy and good dynamic regulation. The device allows a high degree of flexibility and system optimization, making it an ideal choice for powering today’s advanced systems.
