150mA MicroPower™ High Performance LDO

Electrical Characteristics

VIN = VOUT(NOM) + 1V for VOUT options greater than 1.5V. VIN = 2.5 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. VDO is defined as VIN - VOUT when VOUT is 98% of nominal.

2. For VOUT < 2.3V, VDO = 2.5V - VOUT.
