AMC78L05
100mA / 3-TERMINAL 5V REGULATOR
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications in bold type apply over the operating temperature range of
0^OC ≤ T_J ≤ +150^OC, VIN = 10V, I_OUT = 40mA,C_IN = 0.33µF, C_OUT= 0.1µF, and are for DC characteristics only. (Low
duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.)
