Std EditionTPS7A37 1% High-Accuracy, 1-A, Low-Dropout Regulator with Reverse Current Protection
The TPS7A37xx 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 1.0-µF ceramic output capacitor. The NMOS topology also allows very low dropout.
The TPS7A37xx family uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 20 nA and ideal for portable applications. These devices are protected by thermal shutdown and foldback current limit.
Stable with 1.0 μF or Larger Ceramic Output Capacitor Input Voltage Range: 2.2 V to 5.5 V Ultralow Dropout Voltage: 200 mV max at 1 A Excellent Load Transient Response—Even with Only 1.0-µF Output Capacitor NMOS Topology Delivers Low Reverse Leakage Current Excellent Accuracy: 0.23% Nominal Accuracy 1% Overall Accuracy Over Line, Load, and Temperature Less Than 20 nA typical IQ in Shutdown Mode Thermal Shutdown and Current Limit for Fault Protection
