PG 2 3 Power-Good pin, open-drain output. When the VOUT is below the PG threshold the PG pin is driven low; when the VOUT exceeds the threshold, the PG pin goes into a high-impedance state. To use the PG pin, use a 10k Ω to 1MΩ pull-up resistor to pull it up to a supply of up to 5.5V, which can be higher than the input voltage. VCC 3 4 Bias Input pin, provides input voltage for internal control circuitry. This voltage should be higher than the VIN. EN 4 5 Enable pin. This pin should be driven either high or low and must not be floating. Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode. GND 5 6 Ground. SS 6 7 Soft-Start pin. Connect a capacitor between this pin and the ground to set the soft-start ramp time of the output voltage. If no capacitor is connected, the soft-start time is typically 100µS. FB 7 8 Feedback pin. Connect this pin to an external voltage divider to set the output voltage. OUT 8 9, 10 Regulated Output pin. Thermal Pad — — Solder this pad to large ground plane for increased thermal performance. |
