Dual Low-Dropout Linear Regulators

with RESET or Low-Noise Output in UCSP or QFN

ELECTRICAL CHARACTERISTICS (continued)

(IN = 3.8V, SHDN = IN, CBP = 10nF (MAX8531), TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2: All units are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.

Note 3: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V.

Specification applies only when VOUT ≥ 2.5V.

Typical Operating Characteristics

VOUT1 = 3.3V, VOUT2 = 1.5V, load = 80mA (both output voltages), VIN = 3.8V, COUT_ = 2.2µF, CBP = 0.01µF, CIN = 2.2µF, and TA = +25°C,

unless otherwise noted.
