TPL6305-S

Low-Input, Low-Dropout, 3-A Linear Regulator with Enable Control

Electrical Characteristics

All test conditions: T_J= −40°C to +125°C (typical value at T_J= +25°C), V_IN= V_OUT(NOM)+ 0.4 V or 1.4 V, whichever is greater;

V_EN= 1.1 V, V_OUT(NOM)= 0.5 V, I_OUT= 1 mA, C_IN= 10 µF, C_OUT= 10 µF, C_FF= open, unless otherwise noted.
