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 µA typically in shutdown  
mode and less than 40 µA in sleep mode. Forced  
PWM mode is also available to disable sleep mode.

High Efficiency Sleep Mode  
40 µA Typical Iq in Sleep Mode  
10 µA Typical Iq in Shutdown Mode  
3.0V Minimum Input Voltage  
4.0V to 18V Continuous Input Range  
2.0% Reference Accuracy  
Cycle-by-Cycle Current Limit  
Adjustable Frequency (150 kHz to 500 kHz)  
Synchronizable to an External Clock  
Power Good Flag  
The LM26001B can deliver up to 1.5A of continuous  
load current with a fixed current limit, through the  
internal N-channel switch. The part has a wide input  
voltage range of 4.0V to 18V and can operate with  
input voltages as low as 3V during line transients.  
Forced PWM Function  
Adjustable Soft-Start  
Operating frequency is adjustable from 150 kHz to  
HTSSOP-16 Exposed Pad Package  
Thermal Shut Down  
500 kHz with  
a single resistor and can be  
synchronized to an external clock.  
Other features include Power good, adjustable soft-  
start, enable pin, input under-voltage protection, and  
an internal bootstrap diode for reduced component  
count.
