FEATURES  
DESCRIPTIO  
The LT®1764 is a low dropout regulator optimized for fast  
transient response. The device is capable of supplying 3A  
of output current with a dropout voltage of 340mV. Oper-  
ating quiescent current is 1mA, dropping to <1µA in  
shutdown. Quiescentcurrentiswellcontrolled;itdoesnot  
rise in dropout as it does with many other regulators. In  
addition to fast transient response, the LT1764 has very  
low output voltage noise which makes the device ideal for  
sensitive RF supply applications.  
Optimized for Fast Transient Response  
Output Current: 3A  
Dropout Voltage: 340mV at 3A  
Low Noise: 40µVRMS (10Hz to 100kHz)  
1mA Quiescent Current  
Wide Input Voltage Range: 2.7V to 20V  
No Protection Diodes Needed  
Controlled Quiescent Current in Dropout  
Fixed Output Voltages: 1.5V, 1.8V, 2.5V, 3.3V  
Adjustable Output from 1.21V to 20V  
<1µA Quiescent Current in Shutdown  
Stable with 10µF Output Capacitor  
Reverse Battery Protection  
Output voltage range is from 1.21V to 20V. The LT1764  
regulatorsarestablewithoutputcapacitorsaslowas10µF.  
Internal protection circuitry includes reverse battery pro-  
tection, current limiting, thermal limiting and reverse cur-  
rent protection. The device is available in fixed output  
voltages of 1.5V, 1.8V, 2.5V, 3.3V and as an adjustable  
device with a 1.21V reference voltage. The LT1764 regu-  
lators are available in 5-lead TO-220 and DD packages.
