NOTES: (1) The REG104 does not require a minimum output capacitor for stability. However, transient response can be improved with proper capacitor selection.

(2) Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at VIN = VOUT + 1V

at fixed load.

(3) Not applicable for VOUT less than 2.7V.

(4) Current limit is the output current that produces a 15% change in output voltage from VIN = VOUT + 1V and IOUT = 10mA.

(5) For VIN > 6.5V, see typical characteristic VENABLE vs IENABLE.

(6) The REG104 no longer regulates when VIN < VOUT + VDROP (MAX). In drop-out or when the input voltage is between 2.7V and 2.1V, the impedance from VIN

to VOUT is typically less than 1Ω at TJ = +25°C. See typical characteristic Output Voltage Change vs VIN.

ELECTRICAL CHARACTERISTICS

Boldface limits apply over the specified temperature range, TJ = –40°C to +85°C

At TJ = +25°C, VIN = VOUT + 1V (VOUT = 3.0V for REG104-A), VENABLE = 2V, IOUT = 10mA, CNR = 0.01µF, and COUT = 0.1µF(1), unless otherwise noted.
