DESCRIPTION
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.
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.
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.
