TPS79650DRBR
1 Features 3 Description

The TPS796 family of low-dropout (LDO) low-power

TPS79650DRBR 1• 1-A Low-Dropout Regulator With Enable

linear voltage regulators features high power-supply

TPS79650DRBR • Available in Fixed and Adjustable (1.2 V to 5.5 V) rejection ratio (PSRR), ultralow-noise, fast start-up,

Versions and excellent line and load transient responses in

TPS79650DRBR • High PSRR (53 dB at 10 kHz) small outline, 3 × 3 VSON, SOT223-6, and TO-263

small, 1-μF ceramic capacitor on the output. The

• Fast Start-Up Time (50 μs) family uses an advanced, proprietary BiCMOS

• Stable With a 1-μF Ceramic Capacitor fabrication process to yield extremely low dropout

• Excellent Load and Line Transient Response voltages (for example, 250 mV at 1 A). Each device

achieves fast start-up times (approximately 50 μs with • Very Low Dropout Voltage (250 mV at Full Load,

a 0.001-μF bypass capacitor) while consuming very TPS79630) low quiescent current (265 μA typical). Moreover,

• 3 × 3 VSON PowerPAD™, SOT223-6, and when the device is placed in standby mode, the

TO-263 Packages supply current is reduced to less than 1 μA. The

TPS79630 exhibits approximately 40 μVRMS of output

2 Applications voltage noise at 3.0-V output, with a 0.1-μF bypass

capacitor. Applications with analog components that

• RF: VCOs, Receivers, ADCs

are noise sensitive, such as portable RF electronics,

• Audio benefit from the high PSRR, low noise features, and

• Bluetooth need fast response time. ®
