MIC5248

Not Recommended for new designs

The MIC5248 is an efficient, general purpose 1.2V CMOS voltage regulator with a Power Good output function. The MIC5248 offers better than 3% initial accuracy and constant ground current (typically 100µA) over load. The MIC5248 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. Key features include current limit, thermal shutdown, a push-pull output for faster transient response, and an active clamp to speed up device turnoff. Available in the IttyBitty® SOT-23-5 package....
