300mA MicroPowerTM High Performance LDO Linear Regulator
Electrical Characteristics1
VIN = VOUT(NOM) + 1V for VOUT options greater than 1.5V. VIN = 2.5V for VOUT ≤ 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 AAT3238 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and correla-
tion with statistical process controls.
2. VDO is defined as VIN - VOUT when VOUT is 98% of nominal.
3. For VOUT < 2.1V, VDO = 2.5V - VOUT.
