DESCRIPTION
●The TPS786xx 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 small outline, SOT223-6 and DDPAK-5 packages. Each device in the family is stable, with a small 1-µF ceramic capacitor on the output. The family uses an advanced, roprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 390 mV at 1.5 A).
