5 / 24 page  TPS783 www.ti.com SBVS133A – FEBRUARY 2010 – REVISED NOVEMBER 2014 6.5 Electrical Characteristics At TJ = –40°C to 105°C, VIN = VOUT(nom) + 0.5 V or 2.2 V, whichever is greater; IOUT = 100 μA, VEN = VIN, COUT = 1.0 μF, and fixed VOUT test conditions (unless otherwise noted). Typical values at TJ = 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN Input voltage range 2.2 5.5 V Nominal TJ = 25°C –2% 2% VOUT DC output accuracy Over VIN, IOUT, VOUT + 0.5 V ≤ VIN ≤ 5.5 V, –3.0% ±2.0% 3.0% temperature 100 μA ≤ IOUT ≤ 150 mA ΔVO(ΔVI) Line regulation VOUT(nom) + 0.5 V ≤ VIN ≤ 5.5 V ±1.0% ΔVO(ΔIO) Load regulation 100 μA ≤ IOUT ≤ 150 mA ±1.0% VDO Dropout voltage(1) VIN = 95% VOUT(nom), IOUT = 150 mA 130 250 mV ILIM Output current limit VOUT = 0.90 × VOUT(nom) 150 230 400 mA IOUT = 0 mA 420 800 nA IGND GND pin current IOUT = 150 mA 8 μA IEN EN pin current VIN = VEN = 5.5 V 0.07 40 nA ISHDN(GND) Shutdown current at GND pin VEN ≤ 0.4 V, VIN(min) ≤ VIN < 5.5 V (2) 18 150 nA Shutdown current at OUT pin VIN = open, VEN = 0.4 V, ISHDN(OUT) 137 500 nA (leakage)(3) VOUT = VOUT(nom) VEN(HI) Enable high-level voltage VIN = 5.5 V 1.2 VIN V VEN(LO) Enable low-level voltage VIN = 5.5 V 0 0.4 V f = 10 Hz 40 dB VIN = 4.3 V, PSRR Power-supply rejection ratio VOUT = 3.0 V, f = 100 Hz 20 dB IOUT = 150 mA f = 1 kHz 15 dB BW = 100 Hz to 100 kHz, VIN = 2.2 V, Vn Output noise voltage 86 μVRMS VOUT = 1.2 V, IOUT = 1 mA COUT = 1.0 μF, VOUT = 10% VOUT(nom) to tSTR Startup time(4) 500 μs VOUT = 90% VOUT(nom) Shutdown, temperature increasing 160 °C Tsd Thermal shutdown temperature Reset, temperature decreasing 140 °C TJ Operating junction temperature –40 125 °C (1) VDO is not measured for devices with VOUT(nom) ≤ 2.3 V because minimum VIN = 2.2 V. (2) VIN(min) = (VOUT(nom) + 0.5 V) or 2.2 V, whichever is greater. (3) See Shutdown in the Application and Implementation section for more details. (4) Time from VEN = 1.2 V to VOUT = 90% (VOUT(nom)). Copyright © 2010–2014, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: TPS783 |
