UC2836D Description

The UC2836D linear controller is optimized for the design of low-cost, low-dropout, linear regulators. Using an external pass element, dropout voltages of less than 0.5V are readily obtained. The UC2836D contains a high gain error amplifier, a 250mA output driver, and a precision reference. In addition, current sense with foldback provides for a 2.5A peak output current dropping to less than 0.5A at a short circuit. The UC2836D is available in fixed, 5V, or adjustable versions. In the fixed 5-volt version, the only external parts required are an external pass element, an output capacitor, and a compensation capacitor. On the adjustable version, the output voltage can be set anywhere from 2.5V to 35V with two external resistors.
