1 Features 3 Description

1 The TPS732 family of low-dropout (LDO) voltage • Stable with No Output Capacitor or Any Value or

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

• Input Voltage Range: 1.7 V to 5.5 V output capacitors with low equivalent series

• Ultralow Dropout Voltage: 40 mV Typical at resistance (ESR), and even allows operation without

250 mA a capacitor. The device also provides high reverse

blockage (low reverse current) and ground pin current • Excellent Load Transient Response—With or

Without that is nearly constant over all values of output Optional Output Capacitor current.

• NMOS Topology Provides Low Reverse Leakage

Current The TPS732 uses an advanced BiCMOS process to

yield high precision while delivering very low dropout

• Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz) voltages and low ground pin current. Current

• 0.5% Initial Accuracy consumption, when not enabled, is less than 1 μA

• 1% Overall Accuracy (Line, Load, and and ideal for portable applications. The extremely low

Temperature) output noise (30 μVRMS with 0.1-μF CNR) is ideal for

powering VCOs. These devices are protected by

• Less Than 1-μA Maximum IQ in Shutdown Mode thermal shutdown and foldback current limit.
