AND MEDICAL 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-ВµF
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 …
