Sales Briefcase
  • The LD49300 is a high-bandwidth, low-dropout, 3.0 A voltage regulator, ideal for powering core voltages of low power microprocessors. The LD49300 implements a dual supply configuration, which guarantees a very low output impedance and a fast transient response. The LD49300 requires a bias input supply and a main input supply, allowing ultra-low input voltages on the main supply rail. The input supply operates from 1.4 V to 5.5 V and bias supply requires between 3 V and 6 V to work properly. The LD49300 offers fixed output voltages from 0.8 V to 1.8 V and adjustable output voltages from 0.8 V. The LD49300 requires a minimum output capacitance for stability, and works optimally with small ceramic capacitors.

    主要特性

    • Input voltage range:
      • VI = 1.4 V to 5.5 V
      • VBIAS = 3 V to 6 V
    • Stable with ceramic capacitors
    • ±1.5% initial tolerance
    • Maximum dropout voltage (VI - VO) 400 mV over the operating temperature range
    • Adjustable output voltage starting from 0.8 V
    • Very fast transient response (up to 10 MHz bandwidth)
    • Excellent line and load regulation specifications
    • Logic-controlled shutdown option
    • Thermal shutdown and current limit protection
    • Junction temperature range: - 25 °C to 125 °C
