STMicroelectronics LD39130S 高精度电压调节器
STMicroelectronics LD39130S 高精度电压调节器以 1.4V 到 5.5V 的输入电压，提供最高达 300mA 的电流，典型压差为 300mV。它有 DFN6 1.2x1.3mm 封装和超小型 CSP 4 引脚封装可供选择，以实现最大程度的空间节约。该器件通过输出上的陶瓷电容进行稳定。非常低的压降、很低的静态电流和低噪声的特性，使其非常适合低功耗电池供电应用。它集成了一块内部逻辑电路，当所需输出电流非常低时，可以让调节器工作在超低功耗模式（绿色模式）下。正常工作模式对瞬变有快速响应，当负载电流增大时即可恢复。使能逻辑功能将 LD39130S 置于关闭模式下，实现低于 0.1μA 的总电流消耗。提供电流折返和热保护。
STMicroelectronics LD39130S High Accuracy Voltage Regulator is available in compact DFN6 and CSP4 packages, ideal for space-constrained applications.
