lmz12002tzx-adj National Semiconductor Corporation, lmz12002tzx-adj Datasheet - Page 5

• Manufacturer Part Number: lmz12002tzx-adj
• Description: 2a Simple Switcher Power Module With 20v Maximum Input Voltage
• Manufacturer: National Semiconductor Corporation

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test method is per JESD-22-114.
Note 3: Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using Statistical
Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 4: Typical numbers are at 25°C and represent the most likely parametric norm.
Note 5: EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007. See AN-2024 and layout for information on device under test.
Note 6: Theta JA measured on a 1.705” x 3.0” four layer board, with one ounce copper, thirty five 12 mil thermal vias, no air flow, and 1W power dissipation.
