描述
LT®1963A 系列是低壓差穩壓器，專為實現快速瞬態響應而優化。這些器件可提供 1.5A 的輸出電流和一個 340mV 的壓差電壓。工作靜態電流為 1mA，并在停機模式中降至 1μA 以下。靜態電流處于良好受控狀態，與采用其他許多穩壓器不同，它在壓降條件下并不上升。除了快速瞬態響應之外，LT1963A 穩壓器還具有非常低的輸出噪聲，因而使其非常適合于敏感的 RF 電源應用。
輸出電壓范圍為 1.21V 至 20V。LT1963A 穩壓器可在采用低至 10μF 的輸出電容器時實現穩定。內部保護電路包括反向電池保護、電流限制、熱限制和反向電流保護。該器件可提供 1.5V、1.8V、2.5V、3.3V 的固定輸出電壓，并可用作一款具 1.21V 基準電壓的可調型器件。LT1963A 穩壓器采用 5 引腳 TO-220、DD、3 引腳 SOT-223、8 引腳 SO 和 16 引腳 TSSOP 封裝。
