150mA MicroPower™ High Performance LDO

Electrical Characteristics

V_IN= V_OUT(NOM)+ 1V for V_OUToptions greater than 1.5V. V_IN= 2.5 for V_OUT≤1.5V. I_OUT= 1mA, C_OUT= 2.2µF,

C_IN= 1µF, T_A= -40°C to +85°C, unless otherwise noted. Typical values are T_A= 25°C.

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

2. For V_OUT< 2.3V, V_DO= 2.5V - V_OUT
