description
This device is designed to have a fast transient response and be stable with 1-
μ
F 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
μ
A 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.
