MIC5213数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The MIC5213 is a µCap 80mA linear voltage regulator in the Teeny™ SC-70 package. Featuring half the footprint of the standard SOT-23 package, this Teeny™ SC-70 regulator has very low dropout voltage (typically 20mV at light loads and 300mV at 80mA) and very low ground current (225µA at 20mA output). It also offers better than 3% initial accuracy and includes a logic-compatible enable input.The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The outputs typically require only 0.47µF of output capacitance for stability.Designed especially for handheld, battery-powered devices, the MIC5213 can be controlled by a CMOS- or TTL-compatible logic signal. When disabled, power consumption drops nearly to zero. If on-off control is not required, the enable pin may be tied to the input for 3-terminal operation. The ground current of the MIC5213 increases only slightly in dropout, further prolonging battery life. Key MIC5213 features include current limiting, over-temperature shutdown, and protection against reversed battery.The MIC5213 is available in 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, and 5.0V fixed voltages.

简介

MIC5213属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5213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。
