FEATURES

• 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

150mV at an output current of 3A for the TPS75833)

• VREF and Pinout Compatible with MIC29302 and is directly proportional to the output current.

(TPS758A01) Additionally, since the PMOS pass element is a

voltage-driven device, the quiescent current is very

• 3% Tolerance Over Specified Conditions for two key specifications yield a significant

Fixed-Output Versions improvement in operating life for battery-powered

systems.

• Available in 5-Pin TO-220 and TO-263

Surface-Mount Packages The device is enabled when EN (enable) is

• Thermal Shutdown Protection connected to a high voltage level (> 2V). Applying a

low voltage level (< 0.7V) to EN shuts down the

regulator, reducing the quiescent current to less than

1μA at TJ = +25°C.
