UC2835J

高效率稳压器控制器 High Efficiency Regulator Controller

DESCRIPON

The UC1835/6 families of linear controllers are 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.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.
