MIC5156/5157/5158 Micrel, Inc. MIC5156/5157/5158. Super LDO Regulator Controller General Description either , , or 12V. The MIC5158 can be con gured as a xed 5V Controller or programmed to any voltage from The MIC5156, MIC5157, and MIC5158 Super Low-Dropout to 36V using two external resistors. (LDO) Regulator Controllers are single IC solutions for high- current low-dropout linear voltage regulation. Super LDO The MIC5156 is available in an 8-pin DIP or SOIC. The regulators have the advantages of an external N-channel MIC5157 and MIC5158 are available in a 14-pin DIP or SOIC. power MOSFET as the linear pass element. which operate from 40 C to +85 C. 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 Features largest MOSFETs can provide.
