Table 4. ELECTRICAL CHARACTERISTICS

(−40

°C ≤ TJ ≤ 85°C; VIN =VOUT(NOM) + 1 V or 2.5 V, whichever is greater; VEN = 0.9 V, IOUT = 1 mA, CIN =COUT =1 mF.

Typical values are at TJ = +25°C. Min/Max values are specified for TJ = −40°C and TJ =85°C respectively.) (Note 4)

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

4. Performance guaranteed over the indicated operating temperature range by design and/or characterization. Production tested at

TJ =TA =25°C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

5. Characterized when VOUT falls 100 mV below the regulated voltage at VIN =VOUT(NOM) +1V.

6. Shutdown Current is the current flowing into the IN pin when the device is in the disable state.
