2A ADJUSTABLE LINEAR REGULATOR
ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which the device could be permanently damaged.
VIN, VCCA, VFB …................................…....….…………..6V
Output RMS Current, Source or Sink .....………….........…...2A
Storage Temperature ……...................…….. -65°C to 125°C
Lead Temperature (Soldering, 5 sec)……….……….. 260°C
Thermal Resistance(θ_JC)………..……..… 14°C/W (PSOP-8)
Thermal Resistance(θ_JA)……………………….…… 75°C/W
ELECTRICAL CHARACTERISTICS (Unless otherwise stated, these specifications apply T_A=25°C;
VIN=+2.5V and VCCA=+3.3V, VREFEN=1.25V) maximum ratings are stress ratings only and functional device operation is not
implied. (Note 1)
