PG OUT 2 1 IN EN GND 3 5 4 VI PG VO 47 µF + Co(1) 1 µF TPS75901, TPS75915 TPS75918, TPS75925, TPS75933 SLVS318E – DECEMBER 2000 – REVISED MARCH 2004 Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 400 mV at an output current of 7.5 A for the TPS75933) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 125 µA over the full range of output current, 1 mA to 7.5 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. The device is enabled when EN is connected to a low-level voltage. 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 power-good terminal (PG) is an active low, open drain output, which can be used to implement a power-on reset or a low-battery indicator. The TPS759xx is offered in 1.5-V, 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.22 V to 5 V). Output voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The TPS759xx family is available in a 5-pin TO-220 (KC) and TO-263 (KTT) packages.
