3 / 18 page  REG101 3 SBVS026D 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 = 0.01µF, and COUT = 0.1µF(1), unless otherwise noted.

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 1Ω at TJ = +25°C. |
