Limits in standard typeface are for T

J = 25˚C, and limits in boldface type apply over the full operating temperature range. Un-

less otherwise specified: C

1 = C2 = C3 = 0.33 µF; CIN = 15 µF; COUT = 33 µF; VIN = 3.5V.

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device

beyond its rated operating conditions.

Note 2: As long as TA ≤ +85˚C, all electrical characteristics hold true for the 3.0V and 3.3V options at all current loads and the 2.5V option at all loads when VIN ≤

5V. For VIN > 5V with the 2.5V option, the junction temperature rise above ambient is: ∆T = 540IL−23 where IL is in amps. The output current must be derated at

higher ambient temperatures to make sure TJ does not exceed 150˚C when operating the 2.5V option at VIN > 5V.

Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. The machine model is a 200 pF capacitor discharged di-

rectly into each pin.

Note 4: The VOUT pin is forced to 200 mV above the typical VOUT. This is to insure that the internal switches are off.

Note 5: The output capacitor COUT is fully discharged before measurement.
