ELECTRICAL CHARACTERISTICS

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

At TJ = +25°C, VIN = VOUT + 1V, VENABLE = 1.8V, IOUT = 5mA, CNR = 0.01µF, and COUT = 0.1µF(1), unless otherwise noted.

NOTES: (1) The REG113 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) Current limit is the output current that produces a 10% change in output voltage from VIN = VOUT + 1V and IOUT = 5mA.

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

(5) The REG113 no longer regulates when VIN < VOUT + VDROP (MAX). In dropout, the impedance from VIN to VOUT is typically less than 1Ω at TJ = +25°C.

(6) See Figure 7.
