Description

The LD56020 is a high accuracy voltage regulator which provides 0.2 A of current.

It is available in CSP 0.65 x 0.65 mm² package, SOT23-5L, allowing the maximum

space saving.

The device is stabilized with a small ceramic capacitor on input and output. The

ultra-low drop, low quiescent current and short-circuit current foldback make the

LD56020 suitable for low power battery-operated applications.

An enable logic control function puts the LD56020 in shutdown mode allowing a total

current consumption lower than 0.1 μA. Thermal protection is also included.

LD56020J180R属于集成电路（IC） > 线性 + 开关稳压器。意法半导体（ST）集团制造生产的LD56020J180R稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
