Ultra-Low-Power Linear Regulator with 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. • • • • • • Features • • • Datasheet Ultra-low 100pA quiescent current in power down mode Best-in-class quiescent current of 20nA at ILOAD=0 0.5% DC line regulation (typical) Extends battery life Enables power harvesting applications High level of integration minimizes board space Related IDT Smart Power Products • • ZSPM4141 Low operating voltage range: 2.5V to 5.5V Power-Down Mode for 100pA quiescent current Over-current protection: 250mA Output voltage options of 1.2V to 4.2V in 100mV steps (programmed at manufacturing) ZSPM4121 Under-Voltage Load Switch for Smart Battery Management Available Support • • ZSPM4141W12KIT Evaluation Kit Support Documentation Physical Characteristics • Package: 8-pin DFN (2mm x2mm) Typical ZSPM4141 Application Circuits ZSPM4141 Basic (Fixed Output) Application VCC = 2.5V to 5.5V VCC VOUT ZSPM4141 CBYP EN ZSPM4141AI1W12 Variable VOUT via Resistor Divider VCC = 2.5V to 5.5V VOUT = 1.2V to 4.2V COUT 2.2µF (typical) VCC ZSPM4141 CBYP FB VOUT R1 VOUT = 1.2V to 4.2V COUT 2.2µF (typical) FB EN R2 GND © 2016 Integrated Device Technology, Inc.

Recommended Landing Pattern for PCBs Figure 6.1 Recommended Landing Pattern for 8-Pin DFN © 2016 Integrated Device Technology, Inc. 14 January 29, 2016 ZSPM4141 Datasheet 6.2. 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. © 2016 Integrated Device Technology, Inc. 15 January 29, 2016 ZSPM4141 Datasheet Figure 6.4 Conducting Heat Away from the Die using an Exposed Pad Package Mold compound Die Epoxy Die attach Exposed pad Solder 5% - 10% Cu coverage Single Layer, 2oz Cu Ground Layer, 1oz Cu Signal Layer, 1oz Cu Thermal Vias with Cu plating 90% Cu coverage 20% Cu coverage Bottom Layer, 2oz Cu Note: NOT to scale. 6.3. 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. © 2016 Integrated Device Technology, Inc. 16 January 29, 2016 ZSPM4141 Datasheet 7 Ordering Information Ordering Code* Description Package ZSPM4141AI1W12 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 1.2V 8-pin DFN / Reel ZSPM4141AI1W18 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 1.8V 8-pin DFN / Reel ZSPM4141AI1W25 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 2.5V 8-pin DFN / Reel ZSPM4141AI1W30 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 3.0V 8-pin DFN / Reel ZSPM4141AI1W31 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 3.1V 8-pin DFN / Reel ZSPM4141AI1W33 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 3.3V 8-pin DFN / Reel ZSPM4141AI1W42 ZSPM4141 Ultra-Low Power Line Regulator —VOUT factory set to 4.2V 8-pin DFN / Reel ZSPM4141W12KIT ZSPM4141 Evaluation Kit w/Vout adjusting resistors (default 1.2 Vout) Custom VOUT values are also available: 1.2V to 4.2V (typical) in 100mV increments. 8 Related Documents Document ZSPM4141 Feature Sheet ZSPM4141 Evaluation Kit Description ZSPM4141 Application Note—Low Power Battery Control and Voltage Regulator Solutions for Remote Sensor Networks Visit IDT’s website www.IDT.com or contact your nearest sales office for the latest version of these documents. © 2016 Integrated Device Technology, Inc. 17 January 29, 2016 ZSPM4141 Datasheet 9 Document Revision History Revision Date Description 1.00 August 6, 2012 First release. 2.00 January 11, 2013 Addition of variable output illustration and Table 4.1.
