1 / 11 page © Semiconductor Components Industries, LLC, 2006 June, 2006 − Rev. 8 1 Publication Order Number: CS8129/D CS8129 5.0 V, 750 mA Low Dropout Linear Regulator with Lower RESET Threshold The CS8129 is a precision 5.0 V linear regulator capable of sourcing 750 mA. The RESET threshold voltage has been lowered to 4.2 V so that the regulator can be used with 4.0 V microprocessors. The lower RESET threshold also permits operation under low battery conditions (5.5 V plus a diode). The RESET’s delay time is externally programmed using a discrete RC network. During powerup, or when the output goes out of regulation, RESET remains in the low state for the duration of the delay. This function is independent of the input voltage and will function correctly as long as the output voltage remains at or above 1.0 V. Hysteresis is included in the Delay and the RESET comparators to improve noise immunity. A latching discharge circuit is used to discharge the delay capacitor when it is triggered by a brief fault condition. The regulator is protected against a variety of fault conditions: i.e. reverse battery, overvoltage, short circuit and thermal runaway conditions. The regulator is protected against voltage transients ranging from −50 V to +40 V. Short circuit current is limited to 1.2 A (typ). The CS8129 is packaged in a 5 lead TO−220 and a 16 lead surface mount package.
