APPLICATIONS

DESCRIPTION

The TPS791xx family of low-dropout (LDO)

low-power linear voltage regulators features high

power supply rejection ratio (PSRR), ultralow

noise, fast start-up, and excellent line and load

transient responses in a small outline, SOT23,

package. Each device in the family is stable with

a small 1-

µF ceramic capacitor on the output.

The family uses an advanced, proprietary

BiCMOS fabrication process to yield extremely

low dropout voltages (e.g., 38 mV at 100 mA,

TPS79147). Each device achieves fast start-up

times (approximately 63

µs with a 0.001 µF

bypass capacitor) while consuming very low

quiescent current (170

µA typical). Moreover,

when the device is placed in standby mode, the

supply current is reduced to less than 1

µA. The

TPS79118 exhibits approximately 15

output voltage noise with a 0.1

µF bypass

capacitor.

Applications with analog components that are

noise sensitive, such as portable RF electronics,

benefit from the high PSRR and low noise

features as well as the fast response time.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
