Input: Input voltage supply pin. Place a capacitor to ground to
bypass the input supply
Delay: Capacitor to ground sets internal delay timer. Timer delays
power-on reset (POR) output at turn-on and ramp down at turn-off.
Ramp Control: Voltage driven for tracking applications. Capacitor to
ground sets slew rate during start-up.
Enable (Input): CMOS compatible input. Logic high = enable and
logic low = shutdown.
Ground: EP is connected to ground on 3x3 MLF-10L.
Power-on Reset: Open-drain output device indicates when the
output is in regulation. High (open) means device is regulating within
10%. POR onset can be delayed using a single capacitor from Delay
to ground.
Adjustable regulators: Feedback input. Connect to external resistor
voltage divider.
Fixed regulators: Sense pin. Connect to output at load for point-of-
load regulation.
Output Voltage: Output of voltage regulator. Place capacitor to
ground to bypass the output voltage. Minimum load current is 100uA.
Nominal bypass capacitor is 4.7uf ceramic.
