The LM26001MXAX is a synchronous buck switching regulator capable of delivering up to 800 mA output current, while using standard external components. With a set of external resistors and capacitors, the LM26001MXAX allows the output voltage to be adjusted over a 1.212 V to 8 V range.

The LM26001MXAX is a high performance current mode step-down synchronous switching regulator, with a numerical control (OSC) and a built-in high side and low side MOSFET using a peak current mode control (PC Mc) and a frequency control supported by the voltage regulator\'s control circuit. This eliminates the need for a dedicated charge pump circuit.

The LM26001MXAX is designed for both active and standby applications. When the device is active, it uses an internal linear regulator and an internal PWM for power management. When the device is in standby mode, it will use its input voltage to regulate its output voltage. This flexibility provides excellent performance for power sensitive applications.

The LM26001MXAX is capable of delivering up to 800 mA at 3V. It has a power dissipation of 2.4 W (min) and 2.8 W (max). It includes built-in thermal shutdown protection and internal current limit protection. It is robust against input voltage transients, providing an excellent voltage regulation accuracy. It is well suited for step-down regulation applications including switching power supplies and DC to DC converters.

The LM26001MXAX has a very wide operating temperature range of −40°C to +125°C. This allows it to be used in higher temperature application such as automotive and warm-up applications, industrial and medical applications where high temperature ambient is present.

The LM26001MXAX has a number of features that make it an attractive voltage regulator for many applications. It has a low RDS (on) of 2.4 mΩ, low input/output capacitance, low quiescent current and fast over-current protection. It also has a high switching frequency of 1.25 MHz maximized to achieve high efficiency. The wide input voltage range makes it suitable for buck applications.

Overall, the LM26001MXAX is a very efficient, compact and high performance voltage regulator. It can be used in variety of applications such as power supply, battery charging, automotive, industrial, replacement for linear voltage regulators, DC/DC converter and LED lighting. It has a wide operating temperature range of -40°C to 125°C, making it suitable for harsh environmental conditions. With its low RDS (on), fast switching frequency, low quiescent current and flexible design, the LM26001MXAX is the ideal voltage regulator for many applications.
