Description

The LM2931xx are very low drop regulators. The very low drop voltage and the low quiescent current make them particular suitable for low noise, low power applications and in battery powered systems. In the 8 pin configuration (SO-8), fully compatible to the older L78Lxx family, a shut down logic control function is available.

Features

■ Very low dropout voltage (0.15 V typ. at 10 mA load)

■ Low quiescent current (typ. 2.5 mA, at 100 mA load)

■ Output current up to 100 mA

■ Adjustable (from VOUT= 2.5 V only SO-8) and fixed (3.3 V & 5 V) output voltage version

■ Internal current and thermal limit

■ Load dump protection up to 60 V

■ Reverse transient protection up to -50 V

■ Temperature range: -40 to 125 °C

■ Package available: TO-92, DPAK, SO-8 (with inhibit control)

LM2931BZ50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LM2931BZ50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。
