Low-Noise, Low-Dropout, 200mA
Linear Regulator
ELECTRICAL CHARACTERISTICS (continued)
(V_IN = (V_OUT(NOMINAL) + 0.5V) or 2.5V (whichever is greater), T_A = -40°C to +85°C, unless otherwise noted. Typical values are at T_A =
+25°C.) (Note 1)

Note 1: Limits are 100% production tested at T_A = +25°C. Limits over the operating temperature range are guaranteed through
correlation using guaranteed by design (GBD) methods.
Note 2: The dropout voltage is defined as V_IN - V_OUT, when V_OUT is 100mV below the value of V_OUT for V_IN = V_OUT + 0.5V.
Note 3: Time needed for V_OUT to reach 95% of final value.
__________________________________________Typical Operating Characteristics
(V_IN = (V_OUT(NOMINAL) + 0.5V) or 2.5V (whichever is greater), C_IN = 1µF, C_OUT = 2.2µF, C_BP = 0.01µF, T_A = +25°C, unless other-
wise noted.)
