TPS794xx
www.ti.com SLVS349E – NOVEMBER 2001 – REVISED DECEMBER 2005 ULTRALOW-NOISE, HIGH-PSRR, FAST, RF, 250-mA
LOW-DROPOUT LINEAR REGULATORS
FEATURES 250-mA Low-Dropout Regulator With Enable
Available in Fixed and Adjustable (1.2 V to
5.5 V) Versions
High PSRR (60 dB at 10 kHz)
Ultralow Noise (32 ВµVrms, TPS79428)
Fast Start-Up Time (50 Вµs)
Stable With a 2.2-ВµF Ceramic Capacitor
Excellent Load/Line Transient Response
Very Low Dropout Voltage (155 mV at Full
Load)
Available in MSOP-8 and SOT223-6 Packages The TPS794xx family of low-dropout (LDO) 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, MSOP-8 PowerPADв„ў and SOT223-6
packages. Each device in the family is stable with a
small 2.2-ВµF ceramic capacitor on the output. The
family uses an advanced, proprietary BiCMOS
fabrication process to yield extremely low dropout
voltages (for example, 155 mV at 250 mA). Each …
