High Efficiency Maintained Over Three Decades of  
Output Current  
maintain high efficiencies at low output currents. These  
devices drive an external P-channel power MOSFET at  
switchingfrequenciesexceeding400kHzusingaconstant  
off-time current mode architecture providing constant  
ripple current in the inductor.

Low 160µA Standby Current at Light Loads  
Logic Controlled Micropower Shutdown: IQ < 20µA  
Short-Circuit Protection  
Very Low Dropout Operation: 100% Duty Cycle  
High Efficiency in a Small Amount of Board Space  
Output Can Be Externally Held High in Shutdown  
Available in 8-Pin SO Package  
The operating current level is user-programmable via an  
external current sense resistor. Wide input supply range  
allows operation from 3.5V* to 14V (16V maximum).  
Constantoff-timearchitectureprovideslowdropoutregu-  
lation limited by only the RDS(ON) of the external MOSFET  
and resistance of the inductor and current sense resistor.  
U
The LTC1147 series incorporates automatic power saving  
Burst Mode operation to reduce switching losses when  
load currents drop below the level required for continuous  
operation. Standby power is reduced to only 2mW at  
VIN = 10V (at IOUT = 0). Load currents in Burst Mode  
operation are typically 0mA to 300mA.
