FAST-TRANSIENT RESPONSE, 3A, LOW-DROPOUT VOLTAGE REGULATORS

Quiescent current is 125 µ A at full load and drops to

less than 1 µ A when the device is disabled. The

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

and is directly proportional to the output current.

Additionally, since the PMOS pass element is a

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

regulator, reducing the quiescent current to less than

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.
