Simplified Schematic

3 Description

The TPS7A20 is an ultra-small, low-dropout (LDO)

linear regulator that can source 300 mA of output

current. The TPS7A20 is designed to provide low

noise, high PSRR, and excellent load line transient

performance that can meet the requirements of RF

and other sensitive analog circuits. Using innovative

design techniques, the TPS7A20 offers an ultra-low

noise performance without the addition of a noise

bypass capacitor. The TPS7A20 also provides the

advantage of low quiescent current, which can be

ideal for any battery-powered applications. The

TPS7A20 can be used for a wide variety of

applications by supporting an input voltage range

from 1.6 V to 6.0 V and a wide output range of 0.8 V

to 5.5 V. The device uses a precision reference circuit

to provide a maximum accuracy of 1.5% over load,

line, and temperature variations

The TPS7A20 features an internal soft-start to lower

the inrush current, thus minimizing the input voltage

drop during start up. The device is stable with small

ceramic capacitors, allowing for a small overall

solution size.

The TPS7A20 has a smart enable input circuit with

an internally controlled pulldown resistor that keeps

the LDO disabled even when the EN pin is left

floating and helps eliminate the external components

used to pulldown the EN pin.
