PRODUCTION DATA
PIN | TYPE | 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 must 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 | Solder this pad to the ground plane for increased thermal performance. |
