Regulated Output Voltage

ELECTRICAL CHARACTERISTICS (continued)

(VCC = 1.53V to 5.5V, VBATT = 3V, reset not asserted, TA = TJ = -40°C to +85°C, COUT = 10µF, unless otherwise noted. Typical val-

ues are at TA = TJ = +25°C.) (Note 2)

Note 2: All devices are 100% production tested at TA = +25°C and TA = +85°C. Limits over temperature are guaranteed by design.

Note 3: VBATT can be 0 anytime or VCC can go down to 0 if VBATT is active (except at startup).

Note 4: Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT when VIN = VOUT + 1V.

Note 5: CEIN to CEOUT resistance is tested with VCC = 5V and VCEIN = 0 or 5V.

Note 6: Use external current-limiting resistor to limit current to 20mA (max).
