Pin Functions

PIN I/O DESCRIPTION
NAME NO.
IN 1, 2 I Input to the device.
EN 5 I Enable pin. Driving this pin high enables the regulator. Driving this pin low puts the regulator into shutdown mode. This pin must not be left unconnected.
SS 7 Soft-Start pin. A capacitor connected on this pin to ground sets the start-up time. If this pin is left unconnected, the regulator output soft-start ramp time is typically 200 μs.
BIAS 4 I Bias input voltage for error amplifier, reference, and internal control circuits.
PG 3 O Power Good pin. An open-drain, active-high output that indicates the status of VOUT. When VOUT exceeds the PG trip threshold, the PG pin goes into a high-impedance state. When VOUT is below this threshold the pin is driven to a low-impedance state. A pullup resistor from 10 kΩ to 1 MΩ should be connected from this pin to a supply of up to 5.5 V. The supply can be higher than the input voltage. Alternatively, the PG pin can be left unconnected if output monitoring is not necessary.
FB 8 I Feedback pin. The feedback connection to the center tap of an external resistor divider network that sets the output voltage. This pin must not be left floating.
OUT 9, 10 O Regulated output voltage. A small capacitor (total typical capacitance ≥ 2.2 μF, ceramic) is needed from this pin to ground to assure stability.
NC N/A I No connection. This pin can be left floating or connected to GND to allow better thermal contact to the top-side plane.
GND 6 I Ground
Thermal Pad I Should be soldered to the ground plane for increased thermal performance.
