300mA/150mA Dual CMOS LDO Linear Regulator

Electrical Characteristics¹(continued)

V_IN= V_OUT(NOM)+ 1.0 V for V_OUToptions greater than 1.5V. V_IN= 2.5V for V_OUT≤ 1.5 V. I_OUT= 1.0mA, C_OUT

= 2.2 µF, C_IN= 1.0 µF, T_A= -40°C to +85°C, unless otherwise noted. Typical values are T_A= 25°C.

Notes:

1: The AAT3242 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: V_DOis defined as V_IN- V_OUTwhen V_OUTis 98% of nominal.

3: For V_OUT<2.3V, V_DO= 2.5 - V_OUT

4: C_IN= 10µF.

5: To calculate minimum input voltage, use the following equation: V_IN(MIN)= V_OUT(MAX)+ V_DO(MAX)as long as V_IN≥ 2.5V.
