High Efficiency Regulator Controller  
DESCRIPTION  
FEATURES  
The UC1835/6 families of linear controllers are optimized for the de-  
sign of low cost, low dropout, linear regulators. Using an external pass  
element, dropout voltages of less than 0.5V are readily obtained.  
These devices contain a high gain error amplifier, a 250mA output  
driver, and a precision reference. In addition, current sense with fold-  
back provides for a 2.5A peak output current dropping to less than  
0.5A at short circuit.  
Complete Control for a High Current,  
Low Dropout, Linear Regulator  
Fixed 5V or Adjustable Output Voltage  
Accurate 2.5A Current Limiting with  
Foldback  
Internal Current Sense Resistor  
These devices are available in fixed, 5V, (UC1835), or adjustable,  
(UC1836), versions. In the fixed 5 volt version, the only external parts  
required are an external pass element, an output capacitor, and a com-  
pensation capacitor. On the adjustable version the output voltage can  
be set anywhere from 2.5V to 35V with two external resistors.  
Remote Sense for Improved Load  
Regulation  
External Shutdown  
Under-Voltage Lockout and Reverse  
Voltage Protection  
Additional features of these devices include under-voltage lockout for  
predictable start-up, thermal shutdown and short circuit current limiting  
to protect the driver device. On the fixed voltage version, a reverse  
voltage comparator minimizes reverse load current in the event of a  
negative input to output differential.  
Thermal Shutdown Protection

(Surface Mount also Available)
