1 LOW DROPOUT LINEAR REGULATOR Description Features The is a low dropout three-terminal regulator. The has been optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±%. Onchip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature. The is available in.v,.5v,.8v,.5v, 3.3V, 5.0V fixed output voltage versions and ADJ output voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors. The is available in the industry-standard TO5- Series (including TO5- (3), TO5- (4), and TO5- (5)), SOT89 and SOT3 power packages. Current Limit:.35A (Typ) Output Noise from 0Hz to 0KHz: 0.003% of V OUT PSRR at I OUT = 300mA and f = 0Hz: 70dB Output Voltage Accuracy: ±% (Except.V Version) On-chip Thermal Shutdown Maximum Quiescent Current: I QMAX = 6mA Compatible with Low ESR Ceramic Capacitor Operation Junction Temperature: -0 C to +5 C Totally Lead-Free & Fully RoHS Compliant (Notes & ) Halogen and Antimony Free. Green Device (Note 3) Applications USB Device Add-on Card DVD Player PC Motherboard Notes:. No purposely added lead. Fully EU Directive 00/95/EC (RoHS) & 0/65/EU (RoHS ) compliant.. See for more information about s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green products are defined as those which contain <900ppm bromine, <900ppm chlorine (<500ppm total Br + Cl) and <000ppm antimony compounds.
