Connect this pad to system VIN plane for good thermal conductivity.
Power-OK signal output pin. This pin is an open-drain output used to indicate the status of output
voltage by sensing FB voltage. This pin is pulled low when output voltage is not within the Power-OK
voltage window.
Ground pin of the circuitry. All voltage levels are measured with respect to this pin.
Voltage Feedback Pin. Connecting this pin to an external resistor divider receives the feedbackvoltage
of the regulator.
Output pin of the regulator. Connecting this pin to load and output capacitors (10 F at least) is required
for stability and improving transient response. The output voltage is programmed by the resistor-divider
connected to FB pin. The VOUT can provide 3A (max.) load current to loads. During shutdown, the
output voltage is quickly discharged by an internal pull-low MOSFET.
Main supply input pin for voltage conversions. A decoupling capacitor (
connected near this pin to filter the voltage noise and improve transient response. The voltage on this
pin is monitored for Power-On-Reset purpose.
Bias voltage input pin for internal control circuitry. Connect this pin to a voltage source (+5V
recommended). A decoupling capacitor (1 F typical) is usually connected near this pin to filter the
voltage noise. The voltage at this pin is monitored for Power-On-Reset purpose.
Active-high enable control pin. Applying and holding the voltage on this pin below the enable voltage
threshold shuts down the output. When re-enabled, the IC undergoes a new soft-start process. When
leave this pin open, an internal pull-up current (5 A typical) pulls the EN voltage and enables the
regulator.
