ISL78307_15 Datasheet, PDF (4/9 Pages) Intersil Corporation – 40V, Low Quiescent Current, 50mA Linear Regulator for Automotive Applications
ISL78307
Electrical Specifications Recommended Operating Conditions, unless otherwise noted. VIN = 14V, IOUT = 1mA, CIN = 0.1μF,
COUT = 10μF, TA = TJ = -40°C to +125°C, unless otherwise noted. Typical specifications are at TA = +25°C. Boldface limits apply across the operating
temperature range, -40°C to +125°C. (Continued)

NOTES:
6. Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT when VIN = VOUT + 3V.
7. Enable to Regulation is the time the output takes to reach 95% of its final value with VIN = 14V and EN is taken from VIL to VIH 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.
