... Linear Regulator with Watchdog, RESET, and Wake Up The CS8151 is a precision 5.0 V, 100 mA micro−power voltage regulator with very low quiescent current (400 mA typical at 200 mA load). The 5.0 V output is accurate within ±2% and supplies 100 mA of load current with a typical dropout voltage of 400 mV. ...

... Output Compensation The capacitor value and type should be based on cost, availability, size and temperature constraints. A tantalum or aluminum electrolytic capacitor is best, since a film or CS8151 APPLICATION NOTES ceramic capacitor with almost zero ESR can cause instability. The aluminum electrolytic capacitor is the least expensive solution, but, if the circuit operates at low temperatures (− ...
