Pin Functions

PIN I/O DESCRIPTION
NAME ADJ FIXED
BYPASS 4 4 — An external bypass capacitor connected to this pin, in conjunction with an internal resistor, creates a low-pass filter to further reduce regulator noise.
EN 3 3 I The EN pin is an input which enables or shuts down the device. The enable signal is an active-low digital control that enables the device, so when EN is a logic high (> 2 V), the device is in shutdown mode. When EN is logic low (< 0.7 V), the device is enabled.
FB 5 N/A I This pin is the feedback input voltage for the adjustable device.
GND 2 2 — Regulator ground.
IN 1 1 I The IN pin is the input to the device.
OUT 6 5 O The OUT pin is the regulated output of the device.
