PIN TYPE DESCRIPTION
NAME NO.
BYPASS 4 I/O BYPASS pin to achieve low noise performance. Connecting an external capacitor between BYPASS pin and ground reduces reference voltage noise. See the Section 5.3 section for more information.
GND 2 — Ground
ON/OFF 3 I Enable pin for the LDO. Driving the ON/OFF pin high enables the device. Driving this pin low disables the device. High and low thresholds are listed in the Section 5.5 table. Tie this pin to VIN if unused.
VIN 1 I Input supply pin. Use a capacitor with a value of 1 µF or larger from this pin to ground. See the Section 7.1.2 section for more information.
VOUT 5 O Output of the regulator. Use a capacitor with a value of 2.2 µF or larger from this pin to ground. See the Section 7.1.2 section for more information.
