TPS73701DCQR Datasheet

1A Low-Dropout Regulator with Reverse Current Protection


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.

• Stable with 1.0µF or Larger Ceramic Output Capacitor
• 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
• 1.0% Initial Accuracy
• 3% Overall Accuracy Over Line, Load, and Temperature
• Less Than 20nA typical IQ in 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

• Point of Load Regulation for DSPs, FPGAs,
ASICs, and Microprocessors
• Post-Regulation for Switching Supplies
• Portable/Battery-Powered Equipment
