The • 3A Low-Dropout Voltage Regulator TPS758xx is designed to have fast transient • Available in 1.5V, 1.8V, 2.5V, and 3.3V response for large load current changes. Fixed-Output and Adjustable Versions Because the PMOS device behaves as a low-value • Dropout Voltage Typically 150mV at 3A resistor, the dropout voltage is very low (typically (TPS75833) 150mV at an output current of 3A for the TPS75833) • V REF and Pinout Compatible with MIC29302 and is directly proportional to the output current. Additionally, since the PMOS pass element is a (TPS758A01) voltage-driven device, the quiescent current is very • Low 125µA Typical Quiescent Current low and independent of output loading (typically • Fast Transient Response 125 µA over the full range of output current). These • 3% Tolerance Over Specified Conditions for two key specifications yield a significant improvement in operating life for battery-powered Fixed-Output Versions systems. • Available in 5-Pin TO-220 and TO-263 Surface-Mount Packages The device is enabled when EN (enable) is connected to a high voltage level (> 2V). Applying a • Thermal Shutdown Protection low voltage level (< 0.7V) to EN shuts down the regulator, reducing the quiescent current to less than 1 µA at T J = +25°C. The TPS758xx family of 3A low dropout (LDO) The TPS758xx is offered in 1.5V, 1.8V, 2.5V, and regulators contains four fixed voltage option 3.3V fixed-voltage versions and in an adjustable regulators and an adjustable voltage option version (programmable over the range of 1.22V to regulator. These devices are capable of supplying 3A 5V). Output voltage tolerance is specified as a of output current with a dropout of 150mV maximum of 3% over line, load, and temperature (TPS75833). Therefore, the device is capable of ranges. The TPS758xx family is available in a 5-pin performing a 3.3V to 2.5V conversion. TO-220 (KC) and TO-263 (KTT) packages.
