Thermal Shutdown Response of 5.0V LDO
Conditions: V_IN = 6V, C_IN = 0µF, C_OUT = 1µF
V_OUT
I_LOAD was increased until temperature of die reached about 160°C, at
which time integrated thermal protection circuitry shuts the regulator
off when die temperature exceeds approximately 160°C. The regulator
remains off until die temperature drops to approximately 150°C.
