Dual, 300mA, Low-Noise Linear Regulator
with Independent Shutdown in UCSP or TDFN
ELECTRICAL CHARACTERISTICS (continued)
(VIN = 3.8V, SHDNA = SHDNB = IN_, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All units are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: The dropout voltage is defined as VIN - VOUT when VOUT is 100mV below the nominal value of VOUT. Specification only
applies when VOUT ≥ 2.5V.
Typical Operating Characteristics
(VOUTA = VOUTB = 2.85V, VINA = VINB = 3.8V, COUT = 2.2µF (or 4.7µF for 300mA), CBP = 0.01µF, and CIN = 2.2µF (or 4.7µF for
300mA), unless otherwise noted.)
