www.ti.com SNVS491B – MAY 2007 – REVISED APRIL 2013 LM26001B 1.5A Switching Regulator with High Efficiency Sleep Mode
Check for Samples: LM26001B FEATURES DESCRIPTION The LM26001B is a switching regulator designed for
the high efficiency requirements of applications with
stand-by modes. The device features a low-current
sleep mode to maintain efficiency under light-load
conditions and current-mode control for accurate
regulation over a wide input voltage range. Quiescent
current is reduced to 10 ВµA typically in shutdown
mode and less than 40 ВµA in sleep mode. Forced
PWM mode is also available to disable sleep mode. 1 2 High Efficiency Sleep Mode
