Description
Power Supply Voltage (Input): Requires bypass capacitor to GND.
Signal Power Supply Voltage (Input): Requires bypass capacitor to GND.
EN/DLY (Input): When this pin is pulled higher than the enable threshold, the part
will start up. Below this voltage the device is in its low quiescent current mode.
The pin has a 1µA current source charging it to VIN. By adding a capacitor to this
pin a delay may easily be generated. The enable function will not operate with an
input voltage lower than the minimum voltage specified.
Ramp Control: Capacitor to ground from this pin determines slew rate of output
voltage during start-up. This can be used for tracking capability as well as soft
start. The RC pin cannot be left floating. Use a minimum capacitor value of 470pF
or larger.
Feedback: Input to the error amplifier, connect to the external resistor divider
network to set the output voltage.
Compensation pin (Input): Place a RC network to GND to compensate the device,
see applications section.
Power On Reset (Output): Open-drain output device indicates when the output is
out of regulation and is active after the delay set by the DELAY pin.
Power Ground: Ground
Signal Ground: Ground
DELAY (Input): Capacitor to ground sets internal delay timer. Timer delays power-
on reset (POR) output at turn-on and ramp down at turn-off.
Switch (Output): Internal power MOSFET output switches.
Exposed Pad (Power): Must make a full connection to a GND plane for full output
power to be realized.
