LM26001B是一个开关稳压器的应用程序的高效率的要求而设计的待机模式。 The device features low-current sleep mode to maintain light load conditions and current-mode control to precisely regulate efficiency over a wide input voltage range. 静态电流降至10μA的典型关断模式和小于40μA，在睡眠模式。 Forced PWM mode can also disable sleep mode.
LM26001B可以提供高达1.5A的连续负载电流与固定电流限制，通过内部N沟道开关。 该器件具有4.0V至18V的宽输入电压范围和可以操作的输入电压为3V的低线瞬态期间。
The operating frequency is adjustable from a single resistor from 150 kHz to 500 kHz and can be synchronized to an external clock.
Other features include a good power supply, adjustable soft-start, enable pins, input undervoltage protection, and an internal bootstrap diode to reduce component count.
