SiP21110

Notes:

a. Room = 25 °C, Full = - 40 °C to 85 °C. Derate 5.5 mW/°C for SiP21110 above TA = 70 °C.

b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

d. Dropout voltage is defined as the input-to-output differential voltage at which the output voltage drops 2 % below its nominal value with

constant load. For outputs = 2.2 V, dropout voltage is not applicable due to 2.2 V minimum input voltage requirement.

e. Ground current is specified for normal operation as well as “drop-out” operation.

f. The LDO output range is confined to 2.5 V minimum and 5.0 V maximum as a result of min VIN is 2.2 V. For linear regulator outputs where the

output voltages is less than 2.5 V the dropout voltage does not apply.
