To calculate the minimum input voltage for your maximum output current, use the following formula: VI(min) = VO(max) + VDO (max load) 3. Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time. electrical characteristics over recommended operating free–air temperature range, VI = VO(typ) + 1 V, IO = 1 mA, EN = 0V, Co = 4.7 µF (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TPS79015 TJ = 25°C, 2.7 V < VI < 10 V 1.5 TPS79015 TJ = –40°C to 125°C, 2.7 V < VI < 10 V 1.455 1.545 TPS79018 TJ = 25°C, 2.8 V < VI < 10 V 1.8 TPS79018 TJ = –40°C to 125°C, 2.8 V < VI < 10 V 1.746 1.854 Output voltage (10 µA to 50 mA load) TPS79025 TJ = 25°C, 3.5 V < VI < 10 V 2.5 V g( µ ) (see Note 4) TPS79025 TJ = –40°C to 125°C, 3.5 V < VI < 10 V 2.425 2.575 V TPS79028 TJ = 25°C, 3.8 V < VI < 10 V 2.8 TPS79028 TJ = –40°C to 125°C, 3.8 V < VI < 10 V 2.716 2.884 TPS79030 TJ = 25°C, 4.0 V < VI < 10 V 3 TPS79030 TJ = –40°C to 125°C, 4.0 V < VI < 10 V 2.910 3.090 Quiescent current (GND current) (see Note 4) EN = 0 V, 10 µA < IO < 50 mA, TJ = 25°C 17 µA Quiescent current (GND current) (see Note 4) EN = 0 V, IO = 50 mA, TJ = –40°C to 125°C 28 µA Load regulation EN = 0 V, IO = 10 µA to 50 mA, TJ = 25°C 8 mV Output voltage line regulation ( ∆VO/VO) VO + 1 V < VI ≤ 10 V, TJ = 25°C 0.04 Output voltage line regulation ( ∆VO/VO) (see Notes 4 and 5) VO + 1 V < VI ≤ 10 V, TJ = –40°C to 125°C 0.1 %/V Output noise voltage (TPS79030) BW = 300 Hz to 50 kHz, C(byp) = 0.01 µF, Co = 10 µF, IO = 50 mA, TJ = 25°C 56 µVrms Output current limit VO = 0 V, See Note 4 350 750 mA Standby current EN = VI , 2.7 < VI < 10 V 1 µA Standby current TJ = –40°C to 125°C 2 µA NOTES: 4.
