The TPS731xx family of low-dropout (LDO) linear

1• Stable With or Without Capacitors of All Types

voltage regulators uses a new topology: an NMOS

• Input Voltage Range of 1.7 V to 5.5 V pass element in a voltage-follower configuration. This

• Ultralow Dropout Voltage: 30 mV Typical (150-mA topology is stable using output capacitors with low

Load) equivalent series resistance (ESR), and even allows

• Excellent Load Transient Response—With or operation without a capacitor. The device also

Without Optional Output Capacitor provides high reverse blockage (low reverse current)

and ground pin current that is nearly constant over all

• New NMOS Topology Provides Low Reverse values of output current.

Leakage Current

The TPS731xx uses an advanced BiCMOS process

• Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz) to yield high precision while delivering very low

• 0.5% Initial Accuracy dropout voltages and low ground pin current. Current

• 1% Overall Accuracy Over Line, Load, and consumption, when not enabled, is less than 1 μA

Temperature and ideal for portable applications. The extremely low

output noise (30 μVRMS with 0.1-μF CNR) is ideal for • Less Than 1-μA Maximum IQ in Shutdown Mode powering VCOs. These devices are protected by

• Thermal Shutdown and Specified Minimum and thermal shutdown and foldback current limit.
