1 Features 3 Description

The TPS737xx family of linear low-dropout (LDO)

1• Stable With 1-μF or Larger Ceramic Output

voltage regulators uses an NMOS pass element in a Capacitor voltage-follower configuration. This topology is

• Input Voltage Range: 2.2 V to 5.5 V relatively insensitive to output capacitor value and

• Ultralow Dropout Voltage: 130 mV Typical at 1 A ESR, allowing a wide variety of load configurations.

• Excellent Load Transient Response—Even With Load transient response is excellent, even with a

Only small 1-μF ceramic output capacitor. The NMOS 1-μF Output Capacitor

topology also allows very low dropout.

• NMOS Topology Delivers Low Reverse Leakage

Current The TPS737xx family uses an advanced BiCMOS

process to yield high precision while delivering very

• 1% Initial Accuracy low dropout voltages and low ground pin current.

• 3% Overall Accuracy Over Line, Load, and Current consumption, when not enabled, is less than

Temperature 20 nA and ideal for portable applications. These

• Less Than 20 nA Typical I devices are protected by thermal shutdown and Q in Shutdown Mode

foldback current limit. • Thermal Shutdown and Current Limit for Fault

Protection For applications that require higher output voltage

• Available in Multiple Output Voltage Versions accuracy, consider TI's TPS7A37xx family of 1%

overall accuracy, 1-A low-dropout voltage regulators.
