5 / 11 page  Dual, Low Dropout, 250mA LDO Regulator 5 SGM2027 SG Micro Corp www.sg-micro.com ELECTRICAL CHARACTERISTICS (VIN = VOUT (NOMINAL) + 0.5V or 2.5V (whichever is greater), TA = -40 ℃ to +85℃, typical values are at TA = + 25℃, for each LDO unless otherwise specified.) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Input Voltage VIN 2.5 5.5 V Output Voltage Accuracy IOUT = 0.1mA, TA = +25 ℃ -2 +2 % Maximum Output Current (3) 250 mA Current Limit ILIM 310 500 mA Ground Pin Current IQ EN = 2V, both LDOs No Load 190 295 μA IOUT = 1mA 1 Dropout Voltage (1) IOUT = 250mA 250 350 mV Line Regulation OUT IN OUT V V V VIN = 2.5V or (VOUT + 0.5V) to 5.5V, IOUT = 1mA 0.02 0.15 %/V Load Regulation OUT LOAD OUT V I V IOUT = 0.1mA to 250mA, COUT = 1µF 0.00 4 0.01 %/mA Power Supply Rejection Rate PSRR ILOAD = 50mA, COUT = 1µF, f = 100Hz 71 dB SHUTDOWN VIH 1.5 EN Input Threshold VIL VIN = 2.5V to 5.5V 0.4 V TA = +25 ℃ 0.01 1 EN Input Bias Current IB(SHDN) EN = 0V or EN = 5.5V TA = +85 ℃ 0.01 μA TA = +25 ℃ 0.01 1 Shutdown Supply Current IQ(SHDN) EN1 = EN2 = 0.4V TA = +85 ℃ 0.01 μA Shutdown Exit Delay (2) COUT = 1µF, No Load TA = +25 ℃ 20 μs THERMAL PROTECTION Thermal Shutdown Temperature TSHDN 160 ℃ Thermal Shutdown Hysteresis ΔTSHDN 15 ℃ NOTES: 1. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V. (Only applicable for VOUT = 2.5V to 3.3V) 2. Time needed for VOUT to reach 95% of final value. 3. Each channel provides 300mA of maximum output current when the condition of dissipating heat is good. |
