1. The Junction-to-Ambient Thermal Resistance is determined by PC board copper area per Figure 27.
2. ESD data available upon request.
3. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
4. VO(nom) is the part number voltage option.
5. Noise tests on the LP2951 are made with a 0.01
mF capacitor connected across Pins 7 and 1.
*NCV prefix is for automotive and other applications requiring site and change control.
