产品概述

描述

The LD1117A is a low drop voltage regulator able to provide up to 1 A of output current, available also in adjustable versions (VREF= 1.25 V). In fixed versions, the following output voltages are offered: 1.2 V, 1.8 V, and 3.3 V. The device is supplied in: SOT-223, DPAK and TO-220. Surface mounted packages optimize the thermal characteristics while offering a relevant space saving advantage. High efficiency is assured by an NPN pass transistor. Only a very common 10 μF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 2% at 25 °C.
  • 所有功能

    • Low dropout voltage:
      • 1.15 V typ. @ IOUT= 1 A, 25 °C
    • Very low quiescent current:
      • 5 mA typ. @ 25 °C
    • Output current up to 1 A
    • Fixed output voltage of:
      • 1.2 V, 1.8 V, 3.3 V
    • Adjustable version availability (VREF= 1.25 V)
    • Internal current and thermal limit
    • Only 10 μF for stability
    • Available in ± 2% (at 25 °C) and 4% in full temperature range
    • High supply voltage rejection:
      • 80 dB typ. (at 25 °C)
    • Temperature range: 0 °C to 125 °C
