5 / 31 page  TPS706 www.ti.com SBVS245A – OCTOBER 2014 – REVISED MARCH 2015 6.5 Electrical Characteristics At TJ = –40°C to 125°C, VIN = VOUT(nom) + 1 V or 2.7 V (whichever is greater), IOUT = 1 mA, VEN = 2 V, and CIN = COUT = 2.2-μF ceramic, unless otherwise noted. Typical values are at TJ = 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN Input voltage range 2.7 6.5 V VOUT Output voltage range 1.2 5.0 V VOUT < 3.3 V –2% 2% VOUT(accuracy) DC output accuracy VOUT ≥ 3.3 V, TJ = –40°C to 85°C –1% 1% Line regulation (VOUT(nom) + 1 V, 2.7 V) ≤ VIN ≤ 6.5 V 3 10 mV ΔVOUT VIN = VOUT(nom) + 1.5 V or 3 V (whichever is Load regulation 20 50 mV greater), 100 µA ≤ IOUT ≤ 150 mA 2.8 V ≤ VOUT ≤ 3.3 V, IOUT = 50 mA 295 650 mV VDO Dropout voltage(1)(2) 2.8 V ≤ VOUT ≤ 3.3 V, IOUT = 150 mA 975 1540 mV I(CL) Output current limit(3) VOUT = 0.9 × VOUT(nom) 200 320 500 mA IOUT = 0 mA, VOUT ≤ 3.3 V 1.3 2.55 µA IGND Ground pin current IOUT = 150 mA 350 µA ISHDN Shutdown current VEN ≤ 0.4 V, VIN = 2.7 V 150 nA f = 10 Hz 80 dB PSRR Power-supply rejection ratio f = 100 Hz 62 dB f = 1 kHz 52 dB BW = 10 Hz to 100 kHz, IOUT = 10 mA, Vn Output noise voltage 190 μVRMS VIN = 2.7 V, VOUT = 1.2 V Enable pin high (enabled) 0.9 V VEN(HI) Enable pin high (disabled) 0 0.4 V IEN EN pin current EN = 1.0 V, VIN = 5.5 V 300 nA Reverse current VOUT = 3 V, VIN = VEN = 0 V 10 nA (flowing out of IN pin) IREV Reverse current VOUT = 3 V, VIN = VEN = 0 V 100 nA (flowing into OUT pin) Shutdown, temperature increasing 158 °C Thermal shutdown TSD temperature Reset, temperature decreasing 140 °C Operating junction TJ –40 125 °C temperature (1) VDO is measured with VIN = 0.98 × VOUT(nom). (2) Dropout is only valid when VOUT ≥ 2.8 V because of the minimum input voltage limits. (3) Measured with VIN = VOUT + 3 V for VOUT ≤ 2.5 V. Measured with VIN = VOUT + 2.5 V for VOUT > 2.5 V. 6.6 Timing Requirements At TJ = –40°C to 125°C, VIN = VOUT(nom) + 1 V or 2.7 V (whichever is greater), RL = 47 Ω, VEN = 2 V, and CIN = COUT = 2.2-μF ceramic, unless otherwise noted. Typical values are at TJ = 25°C. PARAMETER MIN TYP MAX UNIT VOUT(nom) ≤ 3.3 V 200 600 µs tSTR Start-up time(1) VOUT > 3.3 V 500 1500 µs (1) Startup time = time from EN assertion to 0.95 × VOUT(nom) and load = 47 Ω.
