TPS73719QDRBRQ1

1 -A低压降稳压器具有反向电流保护 1-A LOW-DROPOUT REGULATOR WITH REVERSE CURRENT PROTECTION

Description

The TPS737xx-Q1 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-µF ceramic output capacitor. The NMOS topology also allows very low dropout.
