Pin Function
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: May be voltage driven for tracking applications or a capacitor
to ground will set the slew rate of output voltage during start-up.
Enable (Input): CMOS compatible input. Logic high = enable, logic low =
shutdown.
Not internally connected.
Ground.
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.
Output Voltage Sense Pin: Connect directly to output pin.
Adjustable regulators: Feedback input. Connect to resistor voltage divider.
Output Voltage: Output of voltage regulator. Place capacitor to ground to
bypass the output voltage. Minimum load current is 100µA. Nominal bypass
capacitor is 10µF.
