PIN TYPE DESCRIPTION
NAME NO.
DELAY 7 O Delay pin. Connect a capacitor to GND to adjust the PG delay time; leave open if the reset function is not needed.
EN 5 I Enable pin. This pin turns the regulator on or off.
If VEN ≥ VEN_HI, the regulator is enabled.
If VEN ≤ VEN_LO, the regulator is disabled.
If not used, the EN pin can be connected to IN. Make sure that VEN ≤ VIN at all times.
FB/NC 2 I This pin is a feedback pin when using an external resistor divider or an NC pin when using the device with a fixed output voltage. When using the adjustable device, this pin must be connected through a resistor divider to the output for the device to function. If using a fixed output this pin can either be left floating or connected to GND.
GND 4 — Ground pin
IN 8 I Regulator input supply pin. A capacitor > 0.1 µF must be tied from this pin to ground to assure stability. Connect a 10-µF ceramic capacitor from IN to GND (as close to the device as possible) to reduce circuit sensitivity to printed-circuit-board (PCB) layout, especially when long input tracer or high source impedances are encountered.
NC 6 — This pin can be left open or tied to any voltage between GND and IN.
OUT 1 O Regulator output pin. A capacitor > 2.2 µF must be tied from this pin to ground to assure stability. Connect a 10-µF ceramic capacitor from OUT to GND (as close to the device as possible) to maximize ac performance.
PG 3 O Power-good pin. Open-collector output; leave open or connect to GND if the power-good function is not needed.
Thermal pad — Solder to printed circuit board (PCB) to enhance thermal performance. Although the thermal pad can be left floating, connecting the thermal pad to the GND plane is highly recommended.
