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
