Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | EN | input | Enable input, active high. Drive above VEN(H)=1.4V to enable the converter; drive below VEN(L)=0.4V to force shutdown (all functions disabled, supply current <1uA). Input low current 1uA @ VEN=5V. |+| 2 | GND | power_in | Device ground. Return for the input/output capacitors and the internal low-side synchronous rectifier. |+| 3 | LX | power_out | Switch-node output to the external inductor. Connects to the drains of the internal main P-channel (RDS(ON) ~270 mOhm) and synchronous N-channel (RDS(ON) ~130 mOhm) power MOSFETs. Absolute max -0.3V to 8.0V. |+| 4 | VIN | power_in | Power supply input, 2.5V to 5.5V (absolute max 8.0V, OVP at ~6.1V). Must be closely decoupled to GND with a 10uF or greater ceramic capacitor. |+| 5 | FB/VOUT | input | Feedback input. On the adjustable LP3201AB5F variant this is FB, tied to an external resistor divider from VOUT to set output voltage per VOUT = 0.6V * (1 + RUP/RDN), internal reference 0.6V. On the fixed-output variants (-12/-18/-33) this pin is tied directly to VOUT for internal feedback sensing.
