Output Capacitor (10

µF)

(TPS7433)

description

This device is designed to have a fast transient response and be stable with 1-

µF capacitors. 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

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.
