描述 Description

The TLS805D1 is a linear voltage regulator featuring wide input voltage range, low drop out voltage and ultra low quiescent current. With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 9 μA, the regulator is perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS805D1LDV50 is the fixed 5 V output version with an accuracy of 2% and output current capability up to 50mA. The new regulation concept implemented in TLS805D1 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the TLS805D1 also suitable to supply automotive systems that need to operate during cranking condition. Internal protection features like output current limitation and overtemperature shutdown are implemented to protect the device against immediate damage due to failures like output short circuit to GND, over-current and over-temperature. The device can be switched on and off by the Enable feature. When the device is switched off, the current consumption is typically less than 1 μA. The output voltage is supervised by the Reset feature, including undervoltage reset and delayed reset release at power-on.

简介

TLS805D1LDV50属于集成电路（IC）的稳压器-线性。由制造生产的TLS805D1LDV50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。
