The CS8126 is a low dropout, high current 5V linear regulator. It is an improved replacement for the CS8156. Improvements include higher accuracy, tighter saturation control, better supply rejection, and enhanced RESET circuitry. 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 onchip filtering has been included to enhance rejection of high frequency transients on all external leads. An active microprocessor RESET function is included on-chip with externally programmable delay time. During power-up, or after detection of any error in the regulated output, the RESET lead will remain in the low
