CS8126

Linear Voltage Regulator, LDO, 750 mA, with Delay and Reset

Overview

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 RESETbar 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 on-chip 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 state for the duration of the delay. Types of errors include short circuit, low input voltage, overvoltage shutdown, thermal shutdown, or others that cause the output to become unregulated. This function is independent of the input voltage and will function correctly with an output voltage as low as 1.0 V. Hysteresis is included in both the reset and Delay comparators for enhanced noise immunity. A latching discharge circuit is used to discharge the Delay capacitor, even when triggered by a relatively short fault condition. This circuit improves upon the commonly used SCR structure by providing full capacitor discharge (0.2 V type).

Note: The CS8126 is lead compatible with the LM2927 and LM2926.
