TYPICAL CHARACTERISTICS (CONTINUED)

VOUT

VSHDN

Measure Rise Time of 3.3V LDO

Conditions: CIN = 1µF, COUT = 1µF, ILOAD = 100mA, VIN = 4.3V,

Temp = 25

°C, Fall Time = 184µS

VSHDN

Measure Rise Time of 5.0V LDO

Conditions: CIN = 1µF, COUT = 1µF, ILOAD = 100mA, VIN = 6V,

Temp = 25

°C, Fall Time = 192µS

VOUT

Thermal Shutdown Response of 5.0V LDO

Conditions: VIN = 6V, CIN = 0µF, COUT = 1µF

ILOAD 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.

VOUT

Measure Fall Time of 3.3V LDO

Conditions: CIN = 1µF, COUT = 1µF, ILOAD = 100mA, VIN = 4.3V,

Temp = 25

°C, Fall Time = 52µS

VOUT

VSHDN

Measure Fall Time of 5.0V LDO

Conditions: CIN = 1µF, COUT = 1µF, ILOAD = 100mA, VIN = 6V,

Temp = 25

°C, Fall Time = 88µS
