1A Low-Dropout Regulator

with Reverse Current Protection

FEATURES

DESCRIPTION

•

Stable with 1.0µF or Larger Ceramic Output

Capacitor

The TPS737xx family of linear low-dropout (LDO)

voltage regulators uses an NMOS pass element in a

voltage-follower configuration. This topology is

relatively insensitive to output capacitor value and

ESR, allowing a wide variety of load configurations.

Load transient response is excellent, even with a

small 1.0µF ceramic output capacitor. The NMOS

topology also allows very low dropout for the die size

used.

•

Input Voltage Range: 2.2V to 5.5V

Ultra-Low Dropout Voltage: 130mV typ at 1A

Excellent Load Transient Response—Even

With Only 1.0µF Output Capacitor

•

NMOS Topology Delivers Low Reverse

Leakage Current

The TPS737xx family uses an advanced BiCMOS

process to yield high precision while delivering very

low dropout voltages and low ground pin current.

Current consumption, when not enabled, is under

1µA and ideal for portable applications. These

devices are protected by thermal shutdown and

foldback current limit.

•

0.5% Initial Accuracy

3% Overall Accuracy Over Line, Load, and

Temperature

•

Less Than 20nA typical I_Qin Shutdown Mode

Thermal Shutdown and Current Limit for

Fault Protection

•

Available in Multiple Output Voltage Versions

– Adjustable Output: 1.20V to 5.5V

– Custom Outputs Available Using Factory

Package-Level Programming

APPLICATIONS

•
