Product Overview

The MIC5156YM is a Super Low-Dropout (LDO) Regulator Controller for high current low-dropout linear voltage regulation. Super LDO™ regulator has the advantages of an external N-channel power MOSFET as the linear pass element. This family features a dropout voltage as low as the RDS(ON) of the external power MOSFET multiplied by the output current. The output current can be as high as the largest MOSFETs can provide. It operates from 3 to 36V. The MIC5156 requires an external gate drive supply to provide the higher voltage needed to drive the gate of the external MOSFET. The regulator output is constant-current limited when the controller detects 35mV across an optional external sense resistor. An active-low open-collector flag indicates a low voltage of 8% or more below nominal output. A shutdown (low) signal to the TTL-compatible enable control reduces controller supply current to less than 1µA while forcing the output voltage to ground.
  • 4.5mA Typical operating current
  • <1µA Typical standby current
  • Low external parts count
  • 1% Initial output voltage tolerance in most configurations
  • 2% Output voltage tolerance over temperature
  • Enable pin to activate or shutdown the regulator
  • Internal gate-to-source protective clamp
  • Constant high-current source
  • Low noise/low-dropout SMPS post regulator
  • High-current, current-limited switch
