4 / 13 page TPPM0125 150mA LOW DROPOUT REGULATOR WITH POK SLVS388 − JULY 2001 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 electrical characteristics, TA= 25°C, VI =5 V, V(EN) = VI, IO = 100 µA, CL =1µF(unless otherwise noted) regulator VO PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Output voltage IO = 25 mA 1.2 V VO Output voltage accuracy IO = 0 −1% 1% VO Output voltage accuracy IO = 50 mA, TA = 0°C to 70°C (see Note 4) −2% 2% IQ Quiescent supply current V(EN) ≤ 0.8 V 1 µA I(GND) Ground terminal current (see Note 5) IO = 0 150 A I(GND) Ground terminal current (see Note 5) IO = 150 mA 150 µA IL Output load current 150 mA I(Limit) Output current limit VO = 0 160 300 mA ∆V(LNR) Line regulation VI = 3 V to 5.25 V 10 mV ∆V(LDR) Load regulation IO = 0.1 mA to150 mA, See Note 6 2% 3% VI − VO Dropout voltage IO = 100 µA 1 V VI − VO Dropout voltage IO = 150 mA 1 V CL Load capacitance ESR and capacitance tradeoffs 1 µF I(REV) Reverse output current on VI VI = GND, VO = regulated voltage 50 µA NOTES: 4. Assured by design, not tested in production. 5. Ground terminal current is the regulator quiescent current drawn from the supply to support the load current. 6. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Devices are tested for load regulation in the load range from 0.1 mA to 150 mA. enable input PARAMETER TEST CONDITIONS MIN TYP MAX UNITS VIL Regulated shutdown VI = 3 V to 5.25 V regulated shutdown 0.8 V VIH Regulated enabled VI = 3 V to 5.25 V regulated enabled 2 V I(EN) Enable input current Shutdown, VIL ≤ 0.8 V 0.01 A I(EN) Enable input current Enabled, VIH ≥ 2 V 0.01 µA Resistance discharge V(EN) ≤ 0.8 V 500 Ω thermal protection (see Note 4) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS T(SD) Thermal shutdown 165 °C T(SDHYS) Hysteresis 15 °C NOTE 4: Assured by design, not tested in production. power okay (see Note 7) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS V(POKLO) Low threshold Output falls % of VO (power NOT okay) 85% V(POKTH) High threshold Output reaches % of VO, starts delay timer (power okay) 90% VOL VO out of regulation Fault condition, IOL = 100 µA 0.4 V Ilkg Leakage current VI = 5 V 1 µA NOTE 7: Power okay is a function of the output voltage being 5% lower than the specified range. The function is a detection of one of the following: over current, over temperature, or dropout. |
