This combination provides high performance at a reasonable cost. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 170 mV at an output current of 200-mA for the TPS7433). This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ = 25°C. The TPS74xx is offered in 1.5-V, 1.8-V, 2.5-V, 3-V, and 3.3-V. Output voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The TPS74xx family is available in 8 pin SOIC package. –50 200 50 0 100 0 t – Time – µs CO = 10 µF TPS7418 LOAD TRANSIENT RESPONSE 0 300 200 100 400 500 700 600 800 900 1000 di/dt = TJ – Junction Temperature – °C 100 0 150 50 –50 300 200 250 TPS7433 DROPOUT VOLTAGE vs JUNCTION TEMPERATURE –25 25 0 50 75 100 125 150 IO = 50 mA IO = 1 mA IO = 75 mA IO = 200 mA VI = 3.2 V 200 mA 25 µs Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
