TPS73028DBVR低压差稳压器 High原装TI

1 Features 3 Description

The TPS730 family of low-dropout (LDO) low-power

1• 200-mA RF Low-Dropout Regulator

With linear voltage regulators features high power-supply Enable rejection ratio (PSRR), low noise, fast start-up, and

• Available in Fixed Voltages from 1.8 V to 3.3 V excellent line and load transient responses in a small

and Adjustable Voltages (1.22 V to 5.5 V) SOT-23 package. NanoStar™ packaging gives an

• High PSRR (68 dB at 100 Hz) ultrasmall footprint as well as an ultralow profile and

package weight, making it ideal for portable • Low Noise (33 μVRMS, TPS73018)

applications such as handsets and PDAs. Each

• Fast Start-Up Time (50 μs) device in the family is stable, with a small, 2.2-μF

• Stable With a 2.2-μF Ceramic Capacitor ceramic capacitor on the output. The TPS730 family

• Excellent Load/Line Transient Response uses an advanced, proprietary BiCMOS fabrication

process to yield low dropout voltages (for example,

2 Applications the device is placed in standby mode, the supply

current is reduced to less than 1 μA. The TPS73018

• RF: VCOs, Receivers, ADCs exhibits approximately 33 μVRMS of output voltage

• Audio noise at 1.8 V output with a 0.01-μF bypass

• Cellular and Cordless Telephones capacitor. Applications with analog components that

are noise-sensitive, such as portable RF electronics, • Bluetooth®

, Wireless LAN benefit from the high PSRR and low-noise features

• Handheld Organizers, PDAs as well as the fast response time.
