TPS731 Description
The TPS731xx family of low-dropout (LDO) linear voltage regulators uses a new topology: an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low equivalent series resistance (ESR), and even allows operation without a capacitor.
TPS731 Key Features
- 1 Stable With or Without Capacitors of All Types
- Input Voltage Range of 1.7 V to 5.5 V
- Ultralow Dropout Voltage: 30 mV Typical (150-mA
- Excellent Load Transient Response-With or
- New NMOS Topology Provides Low Reverse
- Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz)
- 0.5% Initial Accuracy
- 1% Overall Accuracy Over Line, Load, and
- Less Than 1-μA Maximum IQ in Shutdown Mode
- Thermal Shutdown and Specified Minimum and
