TPS7350 单输出 LDO、500mA、固定电压 (5.0V)、集成 SVS、低静态电流
TPS7350 描述
The TPS73xx devices are members of a family of micropower low-dropout (LDO) voltage regulators. They are differentiated from the TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset function. If the precision delayed reset is not required, the TPS71xx and TPS72xx should be considered.
The RESET\ output of the TPS73xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS73xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.
If that occurs, the RESET\ output (open-drain NMOS) turns on, taking the RESET\ signal low. RESET\ stays low for the duration of the undervoltage condition
