3 Description

The TPS796 low-dropout (LDO) low-power linear

voltage regulator features high power-supply rejection

ratio (PSRR), low-noise, fast start-up, and excellent

line and load transient responses in small outline,

3mm × 3mm VSON, SOT223-6, and TO-263

packages. Tis device is stable with a small, 1μF

ceramic capacitor on the output. The TPS796 offers

low dropout voltages (for example, 220mV at 1A).

Applications with analog components that are noise

sensitive (such as portable RF electronics) benefit

from the high-PSRR, low-noise features, and need

fast response time.
