SBVS135A –JUNE 2010–REVISED JUNE 2010

Low-Noise, High-Bandwidth PSRR,

Low-Dropout 1A Linear Regulator

Check for Samples: TPS7A80xx

FEATURES

DESCRIPTION

•

Low-Dropout 1A Regulator with Enable

The TPS7A80xx family of low-dropout linear

regulators (LDOs) offer very high power-supply ripple

rejection (PSRR) at the output. This series of LDOs

•

Available in Multiple Output Versions:

–

Fixed Output Voltages: 0.8V to 5.0V Using

Innovative Factory EEPROM Programming

uses an advanced BiCMOS process and

PMOSFET pass device to achieve very low noise,

excellent transient response, and excellent PSRR

performance.

Adjustable Output Voltages: 0.8V to 6.0V

•

Ultra-High PSRR:

–

63dB at 1kHz

57dB at 100kHz

38dB at 1MHz

The TPS7A80xx is stable with a 4.7mF ceramic output

capacitor, and uses a precision voltage reference and

feedback loop to achieve a worst-case accuracy of

3% over all load, line, process, and temperature

variations.

Low Noise: 15.6 × V_OUTmV_RMStypical (100Hz to

100kHz)

This device is fully specified over the temperature

range of T_J= –40°C to +125°C and is offered in a

3mm × 3mm, SON-8 package with a thermal pad.

•

Stable with a 4.7mF Ceramic Capacitor

Excellent Load/Line Transient Response

3% Overall Accuracy (over Load/Line/Temp)

Typical Application Circuit for Fixed Voltage Versions

Over-Current and Over-Temperature

Protection

Optional 1.0mF input capacitor.

May improve source impedance,

noise, or PSRR.
