FEATURES  
DESCRIPTION  
The LP3997 regulator is designed to meet the  
requirements of portable, battery-powered systems,  
providing accurate output voltage, low noise, and low  
quiescent current. The LP3997 provides 3.3V output  
at up to 250mA load current. The chip architecture is  
capable of providing output voltages as low as 0.8V.  
When switched in shutdown mode, the power  
consumption is virtually zero.  
2
Low 140-mV Dropout at 250-mA Load  
Stable With Ceramic Capacitor.  
Low Noise With Bypass Capacitor  
Less Than 80 µA Typical IQ at 250 mA  
Virtually Zero IQ (Disabled)  
Thermal and Short Circuit Protection  
(1)  
3.3-V Output  
The LP3997 is designed to be stable with space  
saving ceramic output capacitor as small as 1µF.  
(2)  
8-Lead VSSOP Package  
The LP3997 also includes an out-of-regulation error  
flag. When the output is more than 5% below its  
nominal voltage, the error flag sets to low. If a  
capacitor is connected to device’s delay pin, a  
delayed power-on reset signal will be generated.  
APPLICATIONS  
Portable Consumer Electronics  
Cellular Handsets  
Laptop and Palm Computers  
PDAs  
Digital Cameras
