1. The Junction ? to ? Ambient Thermal Resistance is determined by PCB copper area per Figure 29.
2. This device series contains ESD protection and exceeds the following tests:
Human Body Model (HBM), 2000 V, Class 2, JESD22 A114 ? C
Machine Model (MM), 200 V, Class B, JESD22 A115 ? A
Charged Device Model (CDM), 2000 V, Class IV, JESD22 C101 ? C
3. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
4. V O(nom) is the part number voltage option.
5. Noise tests on the LP2951 are made with a 0.01 m F capacitor connected across Pins 7 and 1.
*NCV prefix is for automotive and other applications requiring site and change control.
