ELECTRICAL CHARACTERISTICS

(1)(2)(3) (continued)

Limits in standard typeface are for TA = 25°C. Limits in boldface type apply over the full operating junction temperature range

(–40°C

≤ TJ ≤ +125°C). Unless otherwise noted, specifications apply to LP5907 (all packages) Typical Application Circuit (pg.

(1)

Note: The minimum capacitance should be greater than 0.5

μF over the full range of operating conditions. The capacitor tolerance

should be 30% or better over the full temperature range. The full range of operating conditions for the capacitor in the application should

be considered during device selection to ensure this minimum capacitance specification is met. X7R capacitors are recommended

however capacitor types X5R, Y5V and Z5U may be used with consideration of the application and conditions.

(2)

This specification is guaranteed by design.
