LM26003-xx 3-A Switching Regulator With High Efficiency Sleep Mode  
1 Features  
3 Description  
The LM26003 is a switching regulator designed for  
the high-efficiency requirements of applications with  
standby 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 10.8 µA typically in shutdown  
mode and less than 40 µA in sleep mode. Forced  
PWM mode is also available to disable sleep mode.

LM26003-Q1 is an Automotive-Grade Product  
That is AEC-Q100 Grade 1 Qualified (–40°C to  
+125°C Operating Junction Temperature)  
High-Efficiency Sleep Mode  
40-µA Typical Iq in Sleep Mode  
10.8-µA Typical Iq in Shutdown Mode  
3.0-V Minimum Input Voltage  
4.0-V to 38-V Continuous Input Range  
1.5% Reference Accuracy  
The LM26003 device can deliver up to 3 A of  
continuous load current with a fixed current limit,  
through the internal N-channel switch. The part has a  
wide input voltage range of 4.0 V to 38 V and can  
operate with input voltages as low as 3 V during line  
transients.  
Cycle-by-Cycle Current Limit  
Adjustable Frequency (150 kHz to 500 kHz)  
Synchronizable to an External Clock  
Power Good Flag  
Operating frequency is adjustable from 150 kHz to  
Forced PWM Function  
500 kHz with  
a single resistor and can be  
Adjustable Soft-Start  
synchronized to an external clock.  
20-Pin HTSSOP Package  
Other features include Power Good, adjustable soft-  
start, enable pin, input undervoltage protection, and  
an internal bootstrap diode for reduced component  
count.
