Data Sheet Rev. 2.00 / January 2013 ZSPM4141 Ultra-Low-Power Linear Regulator with Minimal Quiescent Current Technology Power Management Power and Precision ZSPM4141 Ultra-Low-Power Linear Regulator w/ Minimal Quiescent Current Technology Brief Description Benefits The ZSPM4141 is an ultra-low-power linear regulator optimized for minimal quiescent current losses via advanced, proprietary technology. It can improve energy efficiency and reduce heat due to power dissipation because it draws low nA-level quiescent current for light loads, yet it can regulate current loads as high as 200mA. The linear regulated output voltage is factory-configured to an option from 1.2V to 4.2V in 100mV steps. The ZSPM4141 also provides over-current protection.

Multi-Layer PCB Layout The following are guidelines for mounting the exposed pad ZSPM4141 on a multi-layer PCB with ground a plane. In a multi-layer board application, the thermal vias are the primary method of heat transfer from the package thermal pad to the internal ground plane. The efficiency of this method depends on several factors, including die area, number of thermal vias, and thickness of copper, etc. Figure 6.2 Package and PCB Land Configuration for Multi-Layer PCB Solder Pad (Land Pattern) Package Thermal Pad Thermal Vias Package Outline Figure 6.3 JEDEC Standard FR4 Multi-Layer Board – Cross-Sectional View (square) Package Solder Pad 1.5038 - 1.5748 mm Component Trace (2oz Cu) 2 Plane 4 Plane 1.5748mm Component Traces Thermal Via Thermal Isolation Power plane only 1.0142 - 1.0502 mm Ground Plane (1oz Cu) 0.5246 - 0.5606 mm Power Plane (1oz Cu) 0.0 - 0.071 mm Board Base & Bottom Pad Package Solder Pad (bottom trace) Figure 6.4 is a representation of how the heat can be conducted away from the die using an exposed pad package. Each application will have different requirements and limitations, and therefore the user should use sufficient copper to dissipate the power in the system. The output current rating for the linear regulators might need to be de-rated for ambient temperatures above 85°C. The de-rated value will depend on calculated worstcase power dissipation and the thermal management implementation in the application.

Single-Layer PCB Layout Layout recommendation for a single-layer PCB: utilize as much copper area for power management as possible. In a single-layer board application, the thermal pad is attached to a heat spreader (copper areas) by using a low thermal impedance attachment method (solder paste or thermal conductive epoxy). In both of the methods mentioned above, it is advisable to use as much copper trace as possible to dissipate the heat. Figure 6.5 Application Using a Single-Layer PCB Use as much copper area as possible for heat spread Package Thermal Pad Package Outline Important: If the attachment method is NOT implemented correctly, the functionality of the product is not guaranteed. Power dissipation capability will be adversely affected if the device is incorrectly mounted onto the circuit board.
