TPS73250QDCQRQ1

无电容NMOS 250毫安低压降与反向电流保护稳压器 CAP-FREE NMOS 250-mA LOW-DROPOUT REGULATOR WITH REVERSE-CURRENT PROTECTION

DESCRIPON

The TPS73250-Q1 family of low-dropout LDO voltage regulators uses a new topology: an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR, and even allows operation without a capacitor. It also provides high reverse blockage low reverse current and ground pin current that is nearly constant over all values of output current.
