ELECTRICAL CHARACTERISTICS (CONTINUED)

Electrical Characteristics: V_IN= V_OUT+ 1V; I_L= 100 μA; T_J= +25°C, bold values indicate –40°C ≤ T_J≤ +125°C

except 0°C ≤ T_J≤ +125°C for 1.8V ≤ V_OUT≤ 2.5V, unless noted. Note 1

Note 1: Specification for packaged product only.

2: Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total

temperature range.

3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are

tested for load regulation in the load range from 100 µA to 500 mA. Changes in output voltage due to heat-

ing effects are covered by the thermal regulation specification.

4: Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its

nominal value measured at 1V differential.

5: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current

drawn from the supply is the sum of the load current plus the ground pin current.

V_ENis the voltage externally applied to devices with the EN (enable) input pin. SOIC-8 (M) and DDPAK (U)

packages only.

7: Thermal regulation is the change in output voltage at a time “t” after a change in power dissipation is

applied, excluding load or line regulation effects. Speciﬁcations are for a 500 mA load pulse at V_IN= 16V

for t = 10 ms.

C_BYPis an optional, external bypass capacitor connected to devices with a BYP (bypass) or ADJ (adjust)

pin. SOIC-8 (M) and DDPAK (U) packages only.
