TPS7A20

SBVS338E – MARCH 2020 – REVISED DECEMBER 2021

TPS7A20 300-mA, Ultra-Low-Noise, Low-I_Q, High PSRR LDO

1 Features

3 Description

•

Low output voltage noise: 7 µV_RMS

– No noise-bypass capacitor required

High PSRR: 95 dB at 1 kHz

Very low I_Q: 6.5 µA

Input voltage range: 1.6 V to 6.0 V

Output voltage range: 0.8 V to 5.5 V

Output voltage tolerance: ±1.5% (max)

Very low dropout:

– 140 mV (max) at 300 mA (V_OUT= 3.3 V)

– 145 mV (max) at 300 mA (V_OUT= 3.3 V, DBV)

Low inrush current

Smart enable pulldown

Stable with 1-µF minimum ceramic output

capacitor

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 and 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 battery-powered applications. With an input

voltage range of 1.6 V to 6.0 V and an output range of

0.8 V to 5.5 V, the TPS7A20 can be used for a wide

variety of applications. The device uses a precision

reference circuit to provide a maximum accuracy of

1.5% over load, line, and temperature variations.

Packages:

– 1-mm × 1-mm X2SON

– 0.603-mm × 0.603-mm DSBGA

– 2.90-mm × 1.60-mm SOT23-5

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.

2 Applications

•

Smartphones and tablets

IP network cameras

Portable medical equipment

Smart meters and field transmitters

Motor drives

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.
