Key Features  
Low Dropout Positive  
Voltage Regulators  
Low Dropout Voltage  
– 0.8V maximum at 100mA  
– 0.95V maximum at 800mA  
– 20% lower dropout voltage than “1117”  
LDO regulators  
Guaranteed Low Dropout Voltage at Multiple  
Current Levels  
1% Trimmed 2.5V, 3.0V and 3.3V Outputs  
Reduced Quiescent Current: 75µA Maximum  
Short Circuit and Thermal Protection  
Space Saving SOT-223 Surface Mount Package  
“1117” Pin Compatible  
– 800mA  
– 2.5V, 3.0V and 3.3V Output  
The IMP37 series of Low Dropout (LDO) three-terminal voltage regula-  
tors feature guaranteed low dropout voltages at currents up to 0.8A. The  
IMP37 regulator family dropout voltage is guaranteed to be 0.95V or  
lower at 0.8A. At 100mA, the maximum dropout voltage is 0.8V.  
Compared with “1117” type LDOs, the IMP37 has a 20% lower dropout  
voltage.  
Three fixed output voltages are offered: 2.5V, 3.0V and 3.3V. Output volt-  
ages are factory trimmed to within 1% of the nominal value.  
In addition to low dropout voltages, the IMP37 family features greatly  
reduced quiescent operating current. The 75µA maximum specification  
represents an over 100 times improvement over competitive devices.  
Applications  
Devices are short circuit protected, and a thermal protection circuit shuts  
the regulator off should the junction temperature exceed 165°C.  
High-efficiency linear power supplies  
Post regulator for switching supplies  
5V to 3.3V linear regulators  
USB hubs  
The IMP37 is available in low-profile plastic SOT-223 and TO-263  
packages and are pin compatible with fixed “1117” devices.
