TPS715345 采用 SC-70 封装的 50mA 输出 3.45V 高输入电压的 LDO 稳压器
TPS715345 描述
The TPS715xx low-dropout (LDO) voltage regulators offer thebenefits of high input voltage, low-dropout voltage, low-power operation, and miniaturized packaging. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor (≥ 0.47 µF). The low dropout voltage and low quiescent current allow operations at extremely low power levels. Therefore, the devices are ideal for powering battery management ICs. Specifically, since the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery charging ICs.
