AP7361C-33SP-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · ESOP-8

AP7361C-33SP-13 from Diodes Incorporated, in a ESOP-8. 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 OUT power_out Regulator output, fixed 3.3V for the -33 option. Bypass to GND with at least a 2.2µF ceramic capacitor; a larger capacitor improves AC load response. Current capability 1A max, with 1.5A typical current limit and 400mA typical short-circuit foldback.
2 EN input Active-high enable input. VIH ≥ 1.0V enables the regulator, VIL ≤ 0.3V disables it. An internal ~3.0MΩ pull-down resistor holds the device off when EN is left floating; input leakage is ±0.1µA typ.
3 NC unconnected No internal connection. Leave floating or tie to a convenient net for layout; not electrically connected inside the SO-8EP fixed-version package.
4 GND power_in Device ground reference. Also serves as the thermal return; the SO-8EP exposed pad should be soldered to a copper ground plane for the 1190mW package dissipation rating.
5 NC unconnected No internal connection on the SO-8EP fixed-version. (Note: on the SO-8EPR adjustable variant this pin is EN - do not swap in a different variant without re-checking.)
6 NC unconnected No internal connection. Leave floating or tie to a static net.
7 NC unconnected No internal connection. Leave floating or tie to a static net.
8 IN power_in Input supply, 2.2V to 6.0V (absolute max 6.5V). Bypass to GND with at least a 1µF ceramic capacitor placed close to the pin. Feeds the internal pass FET, references and error amplifier.
