LDO4 (A-Type) Electrical Characteristics
Unless otherwise noted, V
IN=VIN2=BATT=3.6V, GND = 0V, CV!N1-2 = 10 F, CLDOx= 1 F, TCXO_EN high. Note VINMIN is the
greater of 3.0V or V
OUT +0.5V. Typical values and limits appearing in normal type apply for TJ = 25°C. Limits appearing in bold-
face
type apply over the entire junction temperature range for operation, T
A = TJ = 40°C to +125°C. (Note 6)
