Overview: www.DataSheet4U.com CS8101 Micropower 5.0 V, 100 mA Low Dropout Linear Regulator with RESET and ENABLE
The CS8101 is a precision 5.0 V micropower voltage regulator with very low quiescent current (70 mA typ at 100 mA load). The 5.0 V output is accurate within ±2.0% and supplies 100 mA of load current with a typical dropout voltage of only 400 mV. Microprocessor control logic includes an ENABLE input and an active RESET. This combination of low quiescent current, outstanding regulator performance and control logic makes the CS8101 ideal for any battery operated, microprocessor controlled equipment. The active RESET circuit includes hysteresis, and operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits by more than 200 mV typ. The logic level compatible ENABLE input allows the user to put the regulator into a shutdown mode where it draws only 20 mA typical of quiescent current. The regulator is protected against reverse battery, short circuit, over voltage, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments. The CS8101 is functionally equivalent to the National Semiconductor LP2951 series low current regulators.
