5 / 24 page  LP3990 www.ti.com SNVS251I – MAY 2004 – REVISED MAY 2013 Electrical Characteristics Unless otherwise noted, VEN =950mV, VIN = VOUT + 1.0V, or 2.0V, whichever is higher. CIN = 1 µF, IOUT = 1 mA, COUT =0.47 µF. Typical values and limits appearing in normal type apply for TJ = 27°C. Limits appearing in boldface type apply over the full junction temperature range for operation, −40 to +125°C.

All electrical characteristics having room-temperature limits are tested during production at TJ = 25°C or correlated using Statistical Quality Control methods. Operation over the temperature specification is guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (2) VIN(MIN) = VOUT(NOM) + 0.5V, or 2.0V, whichever is higher. (3) Dropout voltage is voltage difference between input and output at which the output voltage drops to 100mV below its nominal value. This parameter only for output voltages above 2.0V. (4) This electrical specification is guaranteed by design. (5) The device maintains the regulated output voltage without the load. (6) Short circuit current is measured with VOUT pulled to 0V and VIN worst case = 6.0V. (7) Enable Pin has 1M Ω typical, resistor connected to GND.
