All internal circuitry is designed to operate down to 1V input-to-output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum output current, decreasing at lower load currents. Available in fixed voltages. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. -55ºC < TA < 125ºC (UNLESS OTHERWISE SPECIFIED) Test Conditions 1.5V (Vin-Vout) <25V, 10mA <Iout 2A 1.50V<Vin<15V,Iout=10mA (Vin-Vout) = 15V to 30V 10mA<Iout<Ifull load (Vin-Vout) = 3V 10mA<Iout<Ifull load ∆Vref = 1%, Iout = 2A (Vin-Vout)=5V (Vin-Vout)= 25V Typical value is at Tj =25ºC 1.5V<(Vin-Vout)<25V,10mA<Iout<Ifull load (Vin-Vout)= 25V Vin= 5.0V f=120Hz.Cadj=25µF, Cout=25µF(Tant.), (VinVout)=3V,Iout=5.0A TA=ºC, 30ms Pulse -55ºC,<TJ<+125ºC TA=+125ºC, t=1000hrs TA=25ºC, 10Hz<f<10kHz Surface mount LCC5 (SMD 0.5) package Min 1.225 - 60 TYP Max.

Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. 2) Line and load regulation is guaranteed up to the maximum power dissipation in the package. Input/output differential and the output current determine power dissipation. Guaranteed maximum output power will not be available over the full / input/output voltage range. 3) IFull Load is defined as the maximum value of output load current as a function of the input-to-output voltage. IFull Load is equal to 2.0 Amps. • 221 West Industry Court • Deer Park, NY 11729-4681 • Phone (631) 586-7600 • Fax (631) 242-9798 • • World Wide Web Site - http://www.sensitron.com • E-Mail Address - [email protected] • SHD520130 TECHNICAL DATA DATA SHEET 731, REV. - D ro po ut V oltag e vs O utp ut C u rren t 5V AT 5.0A OUT IN VI N 6.5V ADJ + INPUT/OUTPUT VOLTAGE DIFFERENTIAL (V) 5V, 5 .0 A Re g u la to r 121 Ω 1% + 10µF 365 Ω 1% 10µF* TANTALUM Dropout Voltage 1 TJ = –55°C 1 TJ= 25°C 4 2 3 5 OUTPUT CURRENT (A) 8 7 150°C 25°C 6 5 4 –55°C 3 2 I FU L L L OAD GUARANTEED 1 0 6 0 Minimum Operating Current ∆ I = 5A 0.05 0.00 – 0.05 – 0.10 – 0.15 – 0.20 –50 5 15 20 30 35 10 25 INPUT/OUTPUT DIFFERENTIAL (V) 0 –25 25 50 75 100 125 150 T EMPER ATU RE (°C) Adjust Pin Current 1.27 100 9 6 5 TJ =150°C 4 TJ =25°C 3 2 1 ADJUST PINCURRENT ( µ A) 7 REFERENCE VOLTAGE (V) 90 8 0 100% Load Regulation Temperature Stability 10 MINIMUM OPERATING CURRENT (mA) 50% OUTPUT CURRENT 0.10 9 0°C ≤ T J≤ 125°C 0 0 Short-Circut Current – 55°C≤ T J ≤ 150°C 0 0 10 INDICATES GUARANTEED TEST POINT TJ = 150°C 1 OUTPUT VOLTAGE DEVIATION (%) 2 SHORT-CIRCUIT CURRENT (A) MINIMUN INPUT/OUTPUT DIFFERENTIAL (V) *REQUIRED FOR STABILITY 2 1.26 1.25 1.24 TJ = –55°C 0 5 10 15 20 30 35 25 INPUT/OUTPUT DIFFERENTIAL (V) 1.23 –50 –25 0 25 50 75 100 125 150 TEMPERATURE (°C) 80 70 60 50 40 30 20 10 0 –50 –25 0 25 50 75 100 125 150 TEMPERATURE (°C) • 221 West Industry Court • Deer Park, NY 11729-4681 • Phone (631) 586-7600 • Fax (631) 242-9798 • • World Wide Web Site - http://www.sensitron.com • E-Mail Address - [email protected] • SHD520130 TECHNICAL DATA DATA SHEET 731, REV.
