HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : Preliminary Data Issued Date : 1998.08.01 Revised Date : 2001.01.30 Page No. : 1/3 H7812AM H7812BM Low Current Positive Voltage Regulator Of Surface Mount Device Description The H7812_M series of surface mount device regulators are easyto-use devices suitable for multitude of applications that require a regulated supply of up to 100mA. These regulators feature internal current limiting and thermal shutdown making them remarkably rugged. No external components are required with the 7812_M devices in many applications. These devices offer a substantial performance advantage over the traditional zener diode resistor combination, as output impedance and quiescent current are substantially reduced. • W ide Range Of Available, Fixed Output Voltages • Internal Short-Circuit Current Limiting • Internal Thermal Overload Protection • No External Components Required Absolute Maximum Ratings (Ta=25°C) • Input Voltage................................................... 30 V (5V Through 9V), 35 V (12V Through 18V) • Total Power Dissipation ...........................................................................................

H7812BM
物料型号: - H7812AM和H7812BM是Hi-Sincerity Microelectronics Corp.生产的低压降正电压调节器,采用表面贴装技术。

器件简介: - H7812_M系列是易于使用的表面贴装器件,适用于需要高达100mA的稳定电源供应的多种应用。这些调节器具有内部电流限制和热关闭特性,使得它们非常坚固耐用。在许多应用中,不需要外部组件。

引脚分配: - 3-Lead SOT-89塑料表面贴装封装,引脚1:Vout(输出电压),引脚2:Ground(地),引脚3:Vin(输入电压)。

参数特性: - 输出电压:Tj=25°C时,H7812AM为11.64V至12.36V,H7812BM为11.4V至12.6V。 - 线路调整率:14.5V至27V输入电压下,H7812AM和H7812BM均为180mV。 - 负载调整率:1mA至100mA负载电流下,H7812AM和H7812BM均为100mV。 - 静态电流:Ta=25°C时,H7812AM和H7812BM均为5mA。 - 输出噪声电压:Ta=25°C时,H7812AM和H7812BM均为80uV。 - 纹波抑制:15V至25V输入电压下,H7812AM和H7812BM均为40至54dB。 - 峰值输出电流:Ta=25°C时,H7812AM和H7812BM均为140mA。 - 降额电压:Ta=25°C时,H7812AM和H7812BM均为1.7V。

功能详解: - 这些器件提供了比传统的齐纳二极管电阻组合更大的性能优势,因为输出阻抗和静态电流大大减少。

应用信息: - 应用电路图显示了输入电压必须保持比输出电压高至少2.0V,即使在输入纹波电压的低点时。如果调节器远离电源滤波器和负载,可能需要C1和C2以避免回路振荡。

封装信息: - 使用SOT-89封装,具体尺寸和公差基于1996年5月的规格。引线材料为42合金,镀锡。 - 塑封材料为环氧树脂家族,UL94V-0可燃性固体燃烧等级。
