ELECTRICAL CHARACTERISTICS
Boldface limits apply over the specified temperature range, TJ = –40°C to +85°C.
At TJ = +25°C, VIN = VOUT + 1V (VOUT = 2.5V for REG101-A), VENABLE = 1.8V, IOUT = 2mA, CNR = 0.01F, and COUT = 0.1F(1), unless otherwise noted.

NOTES: (1) The REG101 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 = 2mA.
(4) For VENABLE > 6.5V, see typical characteristic “IENABLE vs VENABLE”.
(5) The REG101 no longer regulates when VIN < VOUT + VDROP (MAX). In drop-out, the impedance from VIN to VOUT is typically less than 1 at TJ = +25°C.
