Maxim Integrated 

MAX8840/MAX8841/MAX8842

Ultra-Low-Noise, High PSRR, Low-Dropout,

150mA Linear Regulators in µDFN

ELECTRICAL CHARACTERISTICS (continued)

(VIN = VOUT + 0.5V, TA = -40°C to +85°C, unless otherwise noted. CIN = 1µF, COUT = 1µF, CBP = 10nF. Typical values are at +25°C;

the MAX8842 is tested with 2.45V output, unless otherwise noted.) (Note 1)

Hysteresis

Note 1: Limits are 100% tested at +25°C. Limits over operating temperature range are guaranteed by design.

Note 2: Dropout is defined as VIN - VOUT when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V.

Note 3: Time needed for VOUT to reach 90% of final value.
