AAT2554
Total Power Solution for Portable Applications
Electrical Characteristics1
VINA = VOUT(NOM) + 1V for VOUT options greater than 1.5V. IOUT = 1mA, COUT = 2.2µF, CIN = 1µF, TA = -40°C to
+85°C, unless otherwise noted. Typical values are TA = 25°C.

1. The AAT2554 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured
by design, characterization, and correlation with statistical process controls.
2. VDO is defined as VIN - VOUT when VOUT is 98% of nominal.
3. For VOUT <2.3V, VDO = 2.5V - VOUT.
