Revision No : 3

Fig.1 Standard Test Circuit

Notes : (1) To specify an output voltage, substitute voltage value for

"XX"

(2) Required for stability. For value given, capacitor must be solid tantalum. If alumininum electrolitics are used,

from power supply filter.

(3) To improve transient response. If large capacitors are used, a high current diode from input to output
