ISL78301_15 Datasheet, PDF (5/10 Pages) Intersil Corporation – 40V, Low Quiescent Current, 150mA Linear Regulator for Automotive Applications

ISL78301
Electrical Specifications Recommended Operating Conditions, unless otherwise noted. V_IN = 14V, I_OUT = 1mA, C_IN = 0.1μF,
C_OUT = 10μF, T_A = T_J = -40°C to +125°C, unless otherwise noted. Typical specifications are at T_A = +25°C. Boldface limits apply across the operating
temperature range, -40°C to +125°C. (Continued)

NOTES:
6. Dropout voltage is defined as (V_IN - V_OUT) when V_OUT is 2% below the value of V_OUT when V_IN = V_OUT + 3V.
7. Enable to Regulation is the time the output takes to reach 95% of its final value with V_IN = 14V and EN is taken from V_IL to V_IH in 5ns. For the
adjustable versions, the output voltage is set at 5V.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
