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.
