Features & Applications

The MIC5158YN is a Super Low-Dropout (LDO) Regulator Controller is a single IC solution for high-current low-dropout linear voltage regulation. Super LDO™ Regulators have the advantages of an external N-channel power MOSFET as the linear pass element.

The MIC5156/7/8 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. The regulator output is constant-current limited when the controller detects 35 mV 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 1 µA while forcing the output voltage to ground.

The MIC5158 can be configured as a fixed 5 V controller or programmed to any voltage from 1.3 V to 36 V using two external resistors. The MIC5158 is available in a SOIC which operate from –40°C to +85°C.

Features:

  • 4.5 mA typical operating current
  • <1 µA typical standby current
  • Low external parts count
  • Optional current limit (35 mV typical threshold)
  • 1% initial output voltage tolerance in most configurations
  • 2% output voltage tolerance over temperature
  • Fixed output voltages of 3.3 V, 5.0 V (MIC5156)
  • Fixed output voltages of 3.3 V, 5.0 V, 12 V (MIC5157)
  • Programmable (1.3 to 36 V) with 2 resistors (MIC5156/8)
  • Internal charge pump voltage tripler (MIC5157/8)
  • Enable pin to activate or shutdown the regulator
  • Internal gate-to-source protective clamp
  • All versions available in DIP and SOP

Applications:

  • Ultrahigh current ultralow dropout voltage regulator
  • Constant high-current source
  • Low parts count 5.0 V to 3.3 V computer supply
  • Low noise/low-dropout SMPS post regulator
  • High-current, current-limited switch
