LM26001/LM26001Q  
1.5A Switching Regulator with High Efficiency Sleep Mode  
General Description  
Features  
The LM26001 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 ef-  
ficiency under light-load conditions and current-mode control  
for accurate regulation over a wide input voltage range. Qui-  
escent 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.  
LM26001Q is an Automotive Grade product that is AEC-  
■
Q100 grade 1 qualified (-40°C to +125°C operating  
junction temperature)

40 µA typical Iq in sleep mode  
10 µA typical Iq in shutdown mode  
3.0V minimum input voltage  
4.0V to 38V continuous input range  
The LM26001 can deliver up to 1.5A of continuous load cur-  
rent with a fixed current limit, through the internal N-channel  
switch. The part has a wide input voltage range of 4.0V to 38V  
and can operate with input voltages as low as 3V during line  
transients.  
1.5% reference accuracy  
Cycle-by-cycle current limit  
Adjustable Frequency (150 kHz to 500 kHz)  
Synchronizable to an external clock  
Operating frequency is adjustable from 150 kHz to 500 kHz  
with a single resistor and can be synchronized to an external  
clock.  
Power Good Flag  
Forced PWM function  
Other features include Power good, adjustable soft-start, en-  
able pin, input under-voltage protection, and an internal boot-  
strap diode for reduced component count.
