Electrical Characteristics (continued)

Unless otherwise noted, typical values are for TA = 25°C, and minimum and maximum limits apply over the full operating

temperature range: –40°C

≤ TJ ≤ +125°C; specifications apply to the Typical Application Circuit with VIN = VOUT(NOM) + 1 V,

VBATT = VOUT(NOM) + 1.5 V or 2.5 V (whichever is higher), IOUT = 1 mA, CVIN = 1 µF, COUT = 2.2 µF, VEN = VBATT.

All voltages are with respect to the potential at the GND pin.

(2)

Minimum and maximum limits are ensured by design, test, or statistical analysis. Typical numbers are not ensured, but do represent the

most likely norm. Unless otherwise specified, conditions for typical specifications are: VIN = VOUT(NOM) + 1 V, VBATT = VOUT(NOM) + 1.5 V

or 2.5 V, whichever is higher, TA = 25°C.

(3)

VOUT(NOM) is the stated output voltage option
