Low-Noise, Low-Dropout, 150mA Linear
Regulators with '2982 Pinout
ELECTRICAL CHARACTERISTICS (continued)
(VIN = VOUT(NOMINAL) + 0.5V or 2.5V (whichever is greater), TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA =
+25°C.) (Note 1)

Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through
correlation using Statistical Quality Control (SQC) Methods.
Note 2: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V. (Only
applicable for VOUT = +2.5V to +5V.)
Note 3: Time needed for VOUT to reach 95% of final value.
__________________________________________Typical Operating Characteristics
(VIN = VOUT(NOMINAL) + 0.5V or 2.5V (whichever is greater), CIN = 1µF, COUT = 1µF, CBP = 0.01µF, TA = +25°C, unless otherwise
noted.)
