Features & Applications

The MIC47100-1.0YML TR is a high speed, Low V IN LDO capable of delivering up to 1 A and designed to take advantage of point of load applications that use multiple supply rails to generate a low voltage, high current power supply. The MIC47100 is stable with only a 1 µF ceramic output capacitor and is available in a thermally enhanced 2 mm × 2 mm MLF ® package thus making it an optimal solution for board-constrained applications.

The MIC47100 has an NMOS output stage offering very low output impedance. The NMOS output stage offers a unique ability to respond very quickly to sudden load changes such as that required by a microprocessor, DSP or FPGA. The MIC47100 consumes little quiescent current and therefore can be used for driving the core voltages of mobile processors, post regulating a core DC/DC converter in any portable device.

The MIC47100 is available in fixed and adjustable output voltages in the exposed pad MSOP-8 package and the tiny 2 mm × 2 mm MLF ® package with an operating junction temperature range of -40 °C to +125 °C.

Key Features:

  • Operating voltage range:
    • Input Supply: 1.0 V to 3.6 V
    • Bias Supply: 2.3 V to 5.5 V
  • 0.8 V to 2.0 V output voltage range
  • High bandwidth – very fast transient response
  • PSRR >50 dB at 100 kHz
  • Stable with a 1 µF ceramic output capacitor
  • Low dropout voltage of 80 mV at 1 A
  • High output voltage accuracy:
    • +/- 1.5% initial accuracy
    • +/- 2% over temperature
  • Logic level enable input
  • UVLO on both supply voltages for easy turn-on
  • ePad MSOP-8 – small form factor power package
  • Thermally enhanced 2 mm × 2 mm MLF ® – smallest solution

Applications:

  • Simple high-efficiency step-down (buck) regulator
  • Efficient preregulator for linear regulators
  • On-card switching regulators
  • Positive-to-negative converter (inverting buck-boost)
  • Isolated flyback converter using minimum external components
  • Negative boost converter
