5 / 31 page TPS730 www.ti.com SBVS054J – NOVEMBER 2004 – REVISED APRIL 2015 6.5 Electrical Characteristics Over recommended operating temperature range TJ = –40 to +125°C, VEN = VIN, VIN = VOUT(nom) + 1 V (1), I OUT = 1 mA, COUT = 10 μF, CNR = 0.01 μF (unless otherwise noted). Typical values are at 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN Input voltage range(1) 2.7 5.5 V IOUT Continuous output current 0 200 mA VFB Internal reference (TPS73001) 1.201 1.225 1.25 V Output voltage TPS73001 VFB 5.5 – VDO V range VOUT Output voltage accuracy 0 µA ≤ IOUT ≤ 200 mA, 2.75 V ≤ VIN ≤ 5.5 V –2% VOUT(nom) 2% V ΔVOUT(ΔVIN) Line regulation(1) VOUT + 1 V ≤ VIN ≤ 5.5 V 0.05 %/V ΔVOUT(ΔIOUT) Load regulation 0 µA ≤ IOUT ≤ 200 mA, TJ = 25°C 5 mV Dropout voltage(2) VDO IOUT = 200 mA 120 210 mV (VIN = VOUT(nom) – 0.1 V) ICL Output current limit VOUT = 0 V 285 600 mA IGND Ground pin current 0 µA < IOUT < 200 mA 170 250 μA ISHUTDOWN Shutdown current(3) VEN = 0 V, 2.7 V ≤ VIN ≤ 5.5 V 0.07 1 μA IFB FB pin current VFB = 1.8 V 1 μA Power-supply PSRR TPS73028 f = 100 Hz, IOUT = 200 mA, TJ = 25°C 68 dB rejection ratio Output noise BW = 200 Hz to 100 kHz, IOUT = 200 mA, Vn TPS73018 33 μVRMS voltage CNR = 0.01 μF tSTR Start-up time TPS73018 RL = 14 Ω, COUT = 1 µF, CNR = 0.001 μF 50 μs VEN(high) High-level enable input voltage 2.7 V ≤ VIN ≤ 5.5 V 1.7 VIN V VEN(low) Low-level enable input voltage 2.7 V ≤ VIN ≤ 5.5 V 0 0.7 V IEN EN pin current VEN = 0 V –1 1 μA Threshold, VCC rising 2.25 2.65 V UVLO Hysteresis 100 mV (1) Minimum VIN is 2.7 V or VOUT + VDO, whichever is greater. (2) Dropout is not measured for the TPS73018 and TPS73025 since minimum VIN = 2.7 V. (3) For adjustable versions, this applies only after VIN is applied; then VEN transitions high to low.
