文档解析

MIC5203 线性电压调节器专注于高精度和稳定性，提供80mA输出电流，初始精度优于3%，并在宽温度范围内保持低温度系数，确保输出电压的一致性。压差电压在轻载时仅为20mV，在80mA负载时为300mV，支持输入电压范围从2.5V到16V，适应多种电源条件。接地电流低至225μA at 20mA输出，减少了总功耗，而逻辑兼容的enable功能允许外部控制，关闭时功耗近零。该器件优化用于低ESR陶瓷电容器，仅需0.47μF输出电容即可实现稳定操作，避免了使用大型电容器的需求，降低了系统成本和电路板空间。保护特性包括电流限制和过热关机，增强了设备的安全性。MIC5203非常适合数据采集系统、便携式医疗设备和通信模块等对电压稳定性要求高的应用，多种输出电压选项和紧凑封装便于设计集成。

MIC5203

μCap

80mA Low-Dropout Regulator

General Description

The MIC5203 is a µCap 80mA linear voltage regulator with

very low dropout voltage (typically 20mV at light loads and

300mV at 80mA) and very low ground current (225µA at

20mA output), offering better than 3% initial accuracy with

a logic-compatible enable input.

TheµCap 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 hand-held, battery-powered

devices, the MIC5203 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 MIC5203

increases only slightly in dropout, further prolonging

battery life. Key MIC5203 features include current limiting,

overtemperature shutdown, and protection against

reversed battery.

The MIC5203 is available in 2.8V, 3.0V, 3.3V, 3.6V, 3.8V,

4.0V, 4.5V, 4.75V, and 5.0V fixed voltages. Other voltages

are available.
