3 / 26 page REG103 3 SBVS010D 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 REG103-A), VENABLE = 2V, IOUT = 10mA, 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) Not applicable for VOUT less than 2.7V. (4) Current limit is the output current that produces a 10% change in output voltage from VIN = VOUT + 1V and IOUT = 10mA. (5) For VIN > 6.5V, see typical characteristic VENABLE vs IENABLE. (6) Logic low indicates out-of-regulation condition by approximately 10%, or thermal shutdown. (7) The REG103 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. |
