AP7176BSP-13

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

AP7176BSP-13 from Diodes Incorporated, in a SOIC-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PG output Open-drain power-good output that indicates the status of VOUT by monitoring the FB pin, and is pulled low when the voltage is outside the limits, during thermal shutdown, or if VCNTL or VIN goes below its threshold.
2 EN input Enable pin: driving it low disables the part, and when left floating an internal current source pulls it high to enable the part.
3 VIN power_in Power input pin for current supply; connect a decoupling capacitor (≥ 10µF) as close as possible to the pin for noise filtering.
4 VCNTL power_in BIAS supply for the controller, recommended 5V; connect a decoupling capacitor (≥ 1µF) as close as possible to the pin for noise filtering.
5 NC unconnected No connection.
6 VOUT power_out Power output pin.
7 FB input Feedback pin that sets the output voltage via an external resistor divider between VOUT and GND.
8 GND power_in Ground pin; the exposed pad is also connected to GND for good thermal conductivity.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
