Description

L4995 is a family of monolithic integrated 5 V voltage regulators with a low drop voltage at currents of up to 500 mA, available in both 12 and 24 pin packages.

Features

■ Operating DC supply voltage range 5.6V to 31V

■ Low dropout voltage

■ Low quiescent current consumption

■ Reset circuit sensing of output voltage down to 1V

■ Programmable reset pulse delay with external capacitor

■ Programmable watchdog(a) timer with external capacitor

■ Thermal shutdown and short circuit protection

■ Wide temperature range (Tj = -40°C to 150°C)

■ Enable(a) input for enabling/disabling the voltage regulator

L4995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L4995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。
