The CS8126 is a low dropout, high current 5.0 V linear regulator. It is an improved replacement for the CS8156. Improvements include higher accuracy, tighter saturation control, better supply rejection, and enhanced RESETcircuitry. Familiar PNP regulator features such as reverse battery protection, overvoltage shutdown, thermal shutdown, and current limit make the CS8126 suitable for use in automotive and battery operated equipment. Additional on−chip filtering has been included to enhance rejection of high frequency transients on all external leads.
